Autocar is often prophetic. But the author of a technical review of the then new Buick aluminium V8
engine, writing in the issue of 23 September 1960, could have had little idea just how accurate he
was being when he commented, "We will wager that the most widely copied engine of the next 10 years
will be the superb new aluminium V8 by Buick." In fact, it was only a chance encounter with the
engine by Rover managing director Bill Martin-Hurst that led to this particular prophesy being
fulfilled in this country. But fulfilled it has been, with the highly successful Rover V8 engine
powering a wide variety of Leyland vehicles over the past nine years.
Work started on the design of the Buick engine back in 1950, with first experimental engine being
a cast iron unit 3.85 litres capacity. In the same year, a design for aluminium was prepared, with
the displacement going up to 4.15 litres. By 1952, both of these engines had been road tested,
under an overall GM plan to come up with a power unit that would be lighter than conventional cast
iron engines, and which would allow them to build a lighter, better handling car offering improved
fuel consumption with little or no performance penalty. At this time aluminium looked to be the way
for engine manufacturers to go in the search for weight saving since the later, more sophisticated
thin-wall iron casting techniques were then in their infancy. Work started on the present unit at
the GM design laboratories in 1957 with the first unit running in the summer of 1958 before being
finally turned over to the Buick division for production engineering and design.
Buick managed to design an aluminium alloy with a high silicon content that gave wear characteristics
on the engine test bed which were generally superior to cast iron, confounding the critics who said
that they could not have an aluminium cylinder wall with an aluminium piston running in it in a mass
production engine. However, one problem they simply could not overcome was the scuffing of the bores
by the piston rings in a cold start. It was mainly for this reason that Buick elected to go for iron
cylinder liners cast in place in a block with a more modest silicon content in the aluminium alloy.
Buick had ruled out any idea of using wet liners because the American engineering techniques do not
allow for the handwork precision of wet liners in European designs, and they were most concerned
about the problems of water leakage from a poorly sealed liner.
In fact, the feeling against wet liners was so strong that Buick later admitted they would rather
of abandoned the aluminium alloy concept altogether then to go to wet liners. The liners in
production were pre-heated to prevent chilling in the mould and held in place by mandrels as the
block was cast. Buick used gravity casting in metal dies with sand cores for the water jackets.
The problems of varying expansion rates in the metal between block, head, and rockers were solved
by using hydraulic lifters, already common practice in American engineering. The heads of the Buick
unit were also cast in dies with intricate sand cores.
Buick 215 aluminium V8: in this trim it produces approximately 185hp at 4800 rpm.
The engine was installed in a number of well-known American cars after the production troubles were
ironed out, notably the Buick Special, Pontiac Tempest, and also the Oldsmobile F85 Cutlass after
Oldsmobile engineers had designed different pistons, heads and manifoldings. The Buick Special
engine gave 155bhp gross at 4,600 rpm and produced 220 lb.ft. of torque at 2,400 rpm for an all-up
weight of 318lb.
(British V8 editor's note: when British authors, including especially Rover/Leyland marketing hacks,
write about the Buick 215 they tend to omit any mention of higher-spec variants. In actuality, a
very high proportion of General Motors customers selected "optional equipment" high-performance
versions of these engines. The 155bhp, 8.8:1 compression, 2bbl carbureted engine described above
was just the base model. Tens-of-thousands of Buick Specials and all Buick Skylarks were shipped
from the factory with higher-horsepower, higher-compression, 4bbl carbureted engines. Depending on
model year, these engines produced between 185 and 200bhp. Oldsmobile similarly made their
four-barrel, higher compression engine standard on "Cutlass" and an option on the base-model "F85".
The Oldsmobile "Jetfire" variant was turbocharged and produced 215bhp at 4800rpm and 300 ft.lbs. at
3200rpm.)
After all the investment and engineering time that went into the Buick engine, it seems sad that its
useful working life in production was so short. By 1964 the engine had been virtually abandoned with
the more sophisticated thin wall iron casting techniques being perfected and the American
disenchantment with small engines and the compact car. In fact, although 750,000 aluminium engines
were produced in various form, it was also successfully run as a 5 litre engine with the cylinder
liners deleted and the block cast in iron instead of aluminium. A further 750,000 5 litre iron
engines from the same tools were subsequently built.
(British V8 editor's note: It's so hard to communicate the sheer difference in scale between General
Motors and the British auto industry. GM produced more aluminium V8 engines in just three years than
Rover built in total. The 5 litre engine discussed here, better known stateside as the "Buick 300",
was in fact a very, very similar and obviously derivative design although it's a bit of a stretch to
say that the same tools were used to build it. The Buick 300 crankshaft and heads can in fact be
bolted onto a Buick 215 block, and as an interesting aside, the 1964 model year Buick 300 was fitted
with aluminium cylinder heads as standard.)
It was at this stage that the Rover managing director Bill Martin-Hurst took his historic stumble
across an aluminium Buick engine lying on the floor of an experimental shop in the Mercury Marine
Company's base in Wisconsin. Martin-Hurst was in America talking to Mercury about gas turbine
engines for outboard motors, at that time being most anxious to give his ailing gas turbine division
a boost. In fact, when he showed Mercury the drawings of the engine his company produced they were
more interested in the diesel version of the Land-Rover engine than in his turbines. They had a
contract to supply diesels to Chinese fishing junks, and they were having trouble with the Mercedes
diesels they were using to fulfill the contract. The head of the Mercury concern, Cark Kiekhaefer
told Martin-Hurst that the V8 lying on the shop floor was a Buick, an aluminium engine out of a
Skylark that they ad been playing around with for power boat racing purposes.
Martin-Hurst recalls that with a friend he had been taken out in a Skylark on a previous visit to
America, and he had formed the opinion then that it had been 'terribly nice'. His thoughts went
straight back to England with the problems Rover were having with the six cylinder version of the
Rover 2000 which marketing maintained they needed so badly. The prototype had been built, and
Martin-Hurst had driven it, but he was worried that the weight of the big old 3 litre six in the
front of the 2000 made the car extremely nose heavy. 'Is this engine available?' he asked Kiekhaefer
and was told that it had just gone out of production. The engine was measured and weighed against a
Rover 2000 engine which Mercury had already received from Rover, and proved to be just 12 lb heavier
and within an inch of the overall length.
Kiekhaefer told him to go see Ed Rollert at General Motors to ask if he could use the engine in a
Rover car, and in the meantime the Buick that Martin-Hurst had seen was crated up and dispatched to
England. Martin-Hurst went to the New York Motor Show and had breakfast with Ed Rollert who was
'jolly nice' but who said he could not authorize licensing the engine. Rover would have to approach
GM International. Martin-Hurst went there to see Copeland, the ex-head of Vauxhall and told him of
his interest in the unit. Copeland said he would look into the matter.
Back in England, the Buick was sitting in Rover's experimental shop and creating not a little
interest. Martin-Hurst tried to get Peter Wilks to put the V8 in a 2000 body but Wilks resisted,
telling him that everyone was too busy, and that he wasn't to waste everyone's time. It was no good
putting the engine in a car because they would never get permission to use it from GM anyway. But
Martin-Hurst persisted, and it was finally agreed that Ralph Nash in the competitions department
should do the job. The engine was duly installed with little modification and apart from an
over-long propshaft which tended to flex too much, it was a great success.

Martin-Hurst went down to a board meeting in London and without telling Spen King what it was asked
him to drive the car back. King climbed in, started up and then switched off again. 'What have we
here William?' he asked, and Martin-Hurst told him about the V8. Spen drove it back to Rover and
climbed out with the remark that it was the first Rover he had ever driven which was not
underpowered. Martin-Hurst went back to Copeland and discovered that nothing had happened about his
enquiry because GM could not believe they were serious. Martin-Hurst was soon able to convince them
just how serious he was, and with the help of 'AB' they negotiated a license with GM - a generous
license as it turned out, which opened the flood gates of technical information. Up until this point,
Rover had had great trouble getting much information about the engine out of GM, but now they were
able to acquire all the original service records, drawings and 39 complete engines which the Buick
factory still held and which Rover negotiated for a negligible sum.
Then came the problems of taking an American manufactured engine and attempting to manufacture it in
this country with British component suppliers and foundries. Martin-Hurst soon contacted Buick's
chief engine designer, Joe Turlay, who was then within 18 months of retirement. He confided to
Martin-Hurst that he was not doing too much at Buick anymore, being so near to retirement, so
Martin-Hurst asked him to come to England and help in the conversion of the engine to British
manufacture. Turlay said he was worried about his pension, but Rover won GM agreement that his
pension would not be affected, and he and his wife were brought over to England and installed in a
flat in Solihull on a salary of £20,000.
When Turlay arrived he was puzzled by the Rover engineers' insistence on more power and a higher rev
range. The Buick ran out of revs at 4,700 and was getting unhappy at that. Rover wanted at least
5,200 and possibly 5,500. 'Why do you want all those revs?' asked Turlay. 'People just don't drive
like that.' So he was sat alongside a Rover test driver and proceded to hurtle him across country
and up the M6 at over 100mph in those pre-limit days, to show him what sort of treatment the engine
would have to withstand. After that experience he returned shattered, with an insight into what
Rover wanted.
Turlay was invaluable at interpreting the original drawings. Rover could not understand why the
engines did not conform to the drawings. Turlay was able to point out where things had been changed
in production, the changes not being recorded on the original drawings. At one point he wandered
into Martin-Hurst's office and said that he was unhappy. He felt that he was not earning his salary.
'How many people have you talked to this week?' asked the Rover managing director kindly. 'About
half a dozen I suppose.' replied Turlay. 'And what were the questions?' 'Oh, well, they wanted to
know why the crankshaft webs had a smaller radius than we showed on the drawings. I told them that
after we made about 50,000 engines we started to get crankcase breakages, and we discovered that
by reducing the radius of the webs we got around the problem.' 'What do you suppose that sort of
information is worth to Rover? You can't put a price on it!' said Martin-Hurst.
Decisions were soon made about the production of the engine in England. In the first place, the
gravity die casting with liners in place was carried out in America on an old automatic transmission
die casting machine, a transverse machine where the bock was cast on its end. Enquiries were made
about the drawings and the methods were met with the answer that the man who had set it all up had
died long since.
British casters were unhappy about the technique and soon decided that the only feasible method of
production in England was to sand cast the block and then to press fit and shrink the liners in.
There were surprisingly few problems. Birmingham Aluminium got it right almost on the first attempt,
and with very few changes the engine went into production.
Cross section of the V8 unit - note the centre camshaft with hydraulic tappets still
supplied from America to this day.
Rover altered the oil feed to the rocker shaft in an attempt to cut the rocker shaft and rocker arm
wear they were experiencing with test engines. They were very worried by the problem, but Turlay
with his American engineering attitudes to engines was unable to see the need for concern. The
problem was that the underside of the rocker arm was wearing away, and at the same time cutting into
the case-hardened rocker shaft until it had cut quite a groove, but Turlay pointed out that the
hydraulic pushrods took up the slack anyway, and the engine stayed quiet so what was all the
excitement about? The engine would hold together despite the problem for well over 100,000 miles,
so why worry? By that time no one would want the car. Rover engineering was outraged by the
suggestion, and tried in turn anodized rockers, then tin-plated rocker bearings, and eventually
settled on electro-plated nickel for the surfaces.
(British V8 editor's note: both complete rocker-arm-and-shaft assemblies can be replaced in about
one half hour. They're easily accessed by simply removing the valve covers. The replacement parts
are relatively inexpensive. Since the engine is equipped with hydraulic lifters, no valve-lash
readjustment is required. To this day, American engineers still wonder what those Rover engineers
were so worried about!)
They also changed from the American 'Armasteel' specifications for the crankshaft to a nodular
steel, a feature about which Turlay was very dubious.
With Birmingham Aluminium casting the heads and blocks in sand instead of die casting, the Rover
engines were at once in better tune than the original Buicks. When a head is die cast it inevitably
bows and when it is then machined flat the combustion chambers at each end will be smaller in
volumetric capacity than those in the centre. Rover did not have to contend with this problem.
(British V8 editor's note: since the shrinkage of die-castings is predictable and very consistent
from one part to another off a given die design, contending with this "problem" wouldn't have taken
much more than an afternoon.)
The accessories for the engine would also have to be British. Rover looked at and tested a compound
Rochester carburetor, but soon decided that with European cornering forces it was unsuitable as the
engine tended to cut as the fuel centrifuged in the float chamber. Thus the decision was taken to go
with twin SU's although this would mean introducing bulges into the bonnet - something the engineers
had hoped to avoid.
(British V8 editor's note: it meant other things too. SU carbs are fine, but they need to be
synchronized which adds labor and maintenance costs. Furthermore, they tend to need choke enrichment
in warmer weather and for longer in cool weather than American-style carburetors.)
Lucas were also approached about the ignition side (the Buick engine had been fitted with an
AC-Delco single contact breaker distributor) - this would be Lucas's first single-contact breaker
8-cylinder distributor - and just developed in time for final production. A feature of the
distributor was the very long drive shaft, supported in the die cast timing chest on the front of
the engine which also contains the water pump. The lower end of the distributor has to drive the
oil pump, a Hobourn-Eaton unit. The only item of American manufacture in the entire unit remained
the hydraulic tappets principally because the Diesel Equipment Co., of Grand Rapids could turn
them out at such a low price and at such good quality that it simply was not worth going to a
British supplier. The hydraulic tappets are brought across to this day.
Modified Oldsmobile 215 engine from one of Jim Hall's famous Chaparral II racecars, circa 1963.
(Specifically, it's from Chaparral 2A #002 as driven by Hal Sharp. This particular racecar was
later powered by a Chevrolet V8 engine. The Oldsmobile V8 is now owned by D&D Fabrications.)
William Martin-Hurst was convinced that the engine he had bought for Rover was going to power many
models for many years, and he was already eager to see it put to more sporting use. He asked Jack
Brabham, then using the Buick engine in Repco form in his Formula 1 GP cars for a scrap engine, but
Brabham declined. At that time Brabham had won two World Championships with the Repco, the engine
being developed in its final form to a four camshaft unit. But the American engineering firm Traco
were more than happy to show Rover what they could do, and at one stage a 'full house' 350bhp Traco
unit was shipped to Rover for assessment. "I think we still have it," says Martin-Hurst. The
Company made a collection of all the go-faster items available for the engine from Iskenderian
camshafts to Hallibrand manifolds and they assured themselves that if the need arose they could
be certain of having all the development work needed for raising the power of the engine ready to
hand. Sadly that has never really happened at Rover, and it has been left to individuals to play
with the Rover unit to gain the increases in power it is so obviously capable of delivering.
Notable among the development exercises was that of GKN. They took a standard Rover V8, installed
it in the infamous GKN 47D Lotus, with a succession of modifications to manifolds, camshaft, careful
attention to balancing, a longer throw crankshaft, bigger pistons, and lightweight flywheel. GKN
eventually had the engine delivering a remarkable 296bhp at 6,500 rpm. Later on, Bill Shaw entered
a full race Rover 3500 in club racing in this country, with factory support.
The Rover P6 BS prototype (which was renamed "Leyland Eight GE")
There were any number of variations for the V8 in those early days. It was fitted to the
revolutionary P6 BS mid-engined sports car prototype, designed by Spen King and Gordon Bashford,
and killed off in the Leyland merger. This was a most interesting version of the engine. It ran
facing the rear of the car with the final drive case into the sump, driven by a small prop shaft
running from the gearbox at the front of the engine. Power was transmitted to the gearbox from the
end of the crankshaft by Morse chain and a modified Rover 2000 gearbox was used lying on its side.
Rover devised a new exhaust system for the car which gave equal pulses without the need for
cross-over pipes. They also fitted 2" SU carburetors, with none of the usual complicated silencing
air cleaner trunking. The result was a very quick car indeed, topping 140mph, accelerating from
0-60 mph in 7.0 seconds. The engine was mounted on one side, resulting in extra weight on the front
and rear wheels on the right hand side. However, with left hand drive, and the driver only on board,
the car would be perfectly balanced.
(British V8 editor's note: Leyland did in fact "kill off" any hope of a Rover mid-engined Grand
Touring car being advanced to production. However, they didn't exactly kill off the prototype.
Instead, they renamed it the "Leyland Eight GE" and took it to the 1968 New York International
Automobile Show for display in the Leyland booth. Leyland senior management apparently didn't
see value in building up the Rover brand identity in North America in preparation for introducing
the upcoming Rover 3500S model. Instead, they preferred to promote the Leyland company name
generally. Go figure. We've published the original Leyland Eight GE press materials. Please
see the link below.)
Another one-off using the V8 was a styling exercise made by David Bache, Rover styling director,
which was a two door fastback on the 3500, with a rather Chrysler Alpine like front grille and the
nickname 'Gladys'. This car was to have been marketed as the Alvis GTS, but was another victim of
the merger.
The original V8 installation in the 3.5 saloon and coupe proved very successful. The lighter weight
of the unit improved the handling of the big car enormously, and in no time the 3.5s were to be seen
whistling around the country at great rates of knots. The conversion of the engine to 3500 form
announced in April 1968 involved different manifolds, with the down-pipe being taken from the centre
of the exhaust manifold, instead of from the rear end, as in the original Buick and 3.5 installation.
At first the car was available only with automatic transmission, but in 1971 the 3500S was
introduced, featuring a redesigned exhaust system with the down pipes joining into one pipe much
further back down the system. In fact, the two pipes from the manifolds are of larger diameter than
the 3500 pipes and combined with the extra length of down pipe this meant the back pressure was thus
much reduced over the standard 3500. The 3500S also introduced improved SU carburetors, designated
HIF 6 (Horizontal Integral Float-Chamber) which were claimed to provide more stable carburetion
during conditions of hard acceleration, braking and cornering. At the time of the announcement of
the 3500S (in October 1971) Autocar commented that "relieved of the sobering influence of the
torque converter, the engine has assumed a decidedly sporting character. Even so, it has lost none
of its silky smoothness and a delightful flexibility." The car developed 152bhp (DIN) at 5,000 rpm
and 203.5 lb.ft. of torque at 2,750rpm.

One of the more major changes to the engine had come in June 1970 when the Range Rover was announced.
The introduction of the Range Rover unit had called for a new timing chest die to allow for the
raising of the water pump to accommodate a starting handle dog and a power take-off point. The
compression ratio was reduced to a nominal 8.5 to one (the production engines varying under
manufacturing tolerances between 0.25 and 0.75 anyway) from 10.5 in the car form. The reduction in
compression ratio allowed the Range Rover to run on 2 star fuel, fed to the engine through Zenith
CD 2S carburetors on a special manifold, instead of the SU's of the car engine. The air cleaners
were supposed to incorporate a one way valve to allow any water which might find its way into the
air cleaner to drain 'harmlessly away', but on one Range Rover at least Autocar found that it was
possible to drown the engine in an especially deep water splash. The metal fan was changed for a
moulded plastic type (Rover had experienced fatigue failures with fan blades slicing into the bonnet
of cars) and the starter solenoid was moved further up the engine to keep it out of harm's way. The
Range Rover developed a gross maximum of 156bhp at 5,000 rpm with a peak torque of 205 lb.ft. at
3,000 rpm.
Another major production change for the unit came with the ill-fated P76 saloon engine, first
produced in June 1973. This was a fundamentally revised engine from the 3500, featuring an enlarged
block to make a 'square' engine of 3.5 inch bore and stroke. This brought the capacity to 4,416cc
and the engine developed 192bhp at 4,250rpm and 285 lb.ft. of torque at 2,500 rpm, suggesting
improvements above and beyond the capacity change to head design, breathing, and exhaust. The
Australians did much of the development of the unit themselves, no doubt in co-operation with Traco,
and the exact details of what was done, why, and how are not very clear. It is known that they went
for a twin-choke Stromberg carburetor instead of the two SU's and the central manifold design was
fundamentally revised.
One of the most altered engine from the manifolding point of view was for the MGB V8. The design and
development work for the unit was done at Abingdon, and the most obvious difference was the new
inlet manifold moving the carburetors to the back of the unit to permit the retention of the
standard bonnet. The engine used for the MGB V8 (announced in August 1973) had more in common with
the Range Rover unit than the Rover 3500. It shared the same dished pistons and 8.5:1 compression
ratio, but with an AC-Delco alternator instead of the Lucas unit. The SU HIF6 twin carburetors have
forward facing inlet tracts into a plenum chamber in the centre of the Vee, a system which MG
claimed gave them increased low speed torque over the standard unit. The engine met ECE 15
regulations, with bi-metallic strips controlling the temperature of the air flow into the
carburetors. As installed in the MG the unit delivered 137bhp (DIN) and 193 lb.ft. torque at 2,900
rpm.

(Note: the Holley carb and Holley "Hi-Tek" air cleaner aren't "original".)
Another famous application of the V8 in a sports car was of course the Morgan V8. The story of
this car started in 1966 when Peter Wilks asked Peter Morgan to merge with Rover to produce a sports
car fitted with the V8. Morgan said he liked the engine, but he didn't like the idea of a merger.
Wilks agreed, and negotiations for Morgan to use the engine went ahead smoothly until the Leyland
takeover, when there was a major hiccup. Leyland wanted permission from GM to use the engine in a
Triumph sports car, so permission was sought for both the Morgan and the Triumph. GM replied that
they had no objection to Morgan using the engine, but would not commit themselves on the Triumph.
In the meantime, Peter Morgan had Maurice Owen shoehorn a Buick V8 into a modified Plus Four, and a
very successful car it proved to be. It is still owned by the factory.
After two years had gone by, still with no decision, Morgan approached Harry Webster with a view of
getting a meeting with Donald Stokes to try and confirm an agreement. Harry tried to wean Morgan
away from the Rover engine by showing him the range of Triumph engines, but Morgan remained convinced
that the Rover V8 was the unit he wanted. A couple weeks later, Webster came down to the Malvern
factory with George Turnbull, who was to give the final approval. Turnbull went off for a blast
around the hills in the car, came back most impressed with it, and told Morgan "You can have the
engine as long as you don't take too many of them." The car was exhibited at the 1968 Motor Show
and was an immediate hit.
Morgan's use of the engine involves a fair amount of dismantling. The unit comes in a production
line package, and Morgan takes off the power steering pump and alternator since they dispense with
the viscous coupled fan using an electric fan in its place. They alter the clutch operation, taking
the arm through the top of the bellhousing instead of the side, and they fit the original 3.5
manifold with a special exhaust system. Morgan, of course, are still being supplied with V8s in the
latest and most revised form from the SD1, the latest model being the Plus 8-77 with the 5 speed
gearbox.
The use of the faithful old V8 for SD1, the pride of Leyland's new marketing strategies, called for
some fundamental re-thinking. The engineering staff were faced with calls for more power, a higher
rev-limit, and the eventual need to meet strict American emission regulations.
The first step was to alter the valving in the hydraulic tappets to delay the point at which they
started to "pump up", and after that to improve the breathing. Changes were made to the inlet and
more especially to the exhaust manifolds, with dual outlets per bank and much better extractor
effect, and new single valve springs were introduced. To complete the change, after exhaustive
tests, Lucas electronic ignition was fitted. To test the system, Rover had it running for 6,000
miles of city driving, followed by 6,000 miles around the 'de-tox' route, followed by 6,000 miles
at maximum speed around MIRA, all without attention to the ignition. To get the vehicle to work flat
out without wearing out a set of tires around MIRA's banking every 10 laps, they erected a six foot
high box on the roof of the Rover to drag down maximum speed, but still make the engine work on full
throttle. After that they went back and did a further 6,000 miles in traffic. It seems amazing after
all this testing that the ignition is still giving so much trouble in service.
Long nose Champion N12Y plugs were adopted to go with the electronic system. The oil pump design was
improved with higher output especially at lower speeds, and the water pump housing and impeller were
changed to reduce power loss at high speeds. The piston ring depth was reduced to cope with the
higher revs, and the temperature controlled air intake valve was introduced into the air trunking.
The engine develops 155bhp at 5,250 rpm and 198 lb.ft. of torque at 2,500 rpm.
Those then are the major applications of the Rover engine. There have of course been countless other
applications to specials and one-offs, and many developments of the engine in competition work, but
the unit stands out for its reliability, its kindliness to different mounting brackets (nothing
seems to vibrate and fall off in service) and its durability. The army made all sorts of demands on
it for the application to the new military V8 Land Rover, even demanding that the soldiers must be
able to stand on it to service it. It has taken all the abuse without complaint, and sadly for
British engine designers remains one of the best engines we have ever seen in British cars.
