|
| Cooling: | aluminum radiator. Spal 16" electric fan (pulling). |
| Exhaust: | Adrian Akhurst custom ceramic-coated, long-secondary tri-y headers,
with a crossover pipe. Dual Flowmaster mufflers. The tailpipes exit on
either side of the (re-centered) fuel tank. |
| Transmission: | T5 (Ford-spec) 5-speed transmission. 10.4" Centerforce clutch with 2400# pressure
plate. Hydraulic throw-out bearing. Great big custom driveshaft. |
| Rear Axle: | Ford 8" with Currie aluminum gear case and pinion support.
Auburn limited slip differential. 3.25:1, 28-spline axle shafts. |
| Front Susp. : | stock MGB, with uprated (3/4") anti-sway bar. |
| Rear Susp. : | custom-designed three link rear suspension, featuring Bilstein coilover shock
absorbers. Custom Panhard rod. |
| Brakes: | stock master cylinder, supplemented with dual Wilwood (2psi) residual pressure valves. (front) Wilwood calipers and vented/cross-drilled rotors, (rear) Wilwood calipers and cross-drilled rotors (and working parking brake). |
| Wheels/Tires: | Panasport Racing 8-spoke 16" wheels with Bridgestone "Potenza S-03" 225/50ZR16 tires. |
| Body Mods: | although a 1969 bodyshell was used for the conversion, a "rubber bumper" MGB
firewall was grafted-in for increased engine clearance. Holes were cut in the
inner fenders for through-the-fender headers, and the holes were bellmouthed
downward for a clean appearance (and increased strength). Very subtle "mini IMSA"
fender flares were built onto the rear quarterpanels to help accomodate wider
tires. (Fender lips were also rolled upward.) The heelboard stiffener (at the
back of the driveshaft tunnel, under the driveshaft) was removed and replaced
with the deeper-section stiffener from a rubber-bumper MGB. The rear shelf
(above the battery boxes) and the trunk floor were extensively modified to
accomodate three-link rear suspension. For added stiffness, the chassis has
been reinforced from the leaf spring perches forward along the floorboards
to the outer crossmembers. A later-model ('73-'74) MGB front valance, with
oil cooler holes, was installed. The fuel tank was centered to accomodate
symmetrical dual exhaust. (Note: many of the body modifications were completed
by Ken's friend John Mangles, who operates All British Car Repair in St Louis
and who is also a BritishV8 vendor sponsor.) |
| Exterior Trim: | stainless steel wire mesh grille. Late-model ('74-'80) MGB side-view mirrors.
Stayfast convertible top. |
| Interior: | Fiero seats with custom tan leather upholstery by "Mr Mikes", headrest speakers,
electric seat heaters, and with Schroth "Rallye" four-point safety harnesses.
(Note: Schroth harnesses are specially engineered to prevent pelvis and spine damage
due to "submarining" in the event of a severe front accident. Submarining is the
term for what happens if the lower part of the torso slides forward under the
lap belt. Essentially, one of the two shoulder straps is designed to stretch a
prescribed amount so that the body folds over the lap belt, yet with more control
than with a three-point seat belt system.) Earlier-model ('62-'67) MGB "steel"
dashboard, with custom center console and custom-upholstered "eyebrow" (color-matched
to the seats, instead of black). |
| Electrical: | modified Smith's tachometer. Odyssey drycell battery. Delco alternator. Mini starter.
Kenwood AM/FM/CD stereo. |
| Completed: | 2008. |
| Comments: | Ken was an active, enthusiastic, popular, and deeply respected member of the
BritishV8 community. He participated in our annual meets, even when he didn't
have a completed conversion to bring. Ken's masterpiece, the MGB V8 shown here,
was only just completed and being sorted-out when he became ill. Ken passed away
August 5, 2008. We're saddened Ken wasn't able to show off his V8 at BritishV8
2008, but we know he was with us in spirit. The car is now owned by The St
Louis Car Museum, and they've been very generous to support BritishV8 with
the exceptional photographs you see here so that we can honor Ken with this
"How It Was Done" article. |
