Photo: BritishV8: the site for enthusiasts of modified British sports carsA 1969 MGB rebuilt with a stroked Rover-based Buick 215 V8
Ken Biermann transformed a 1969 MGB into a V8-powered sports car built around a bored, stroked Buick 215 aluminum block fitted with Rover-derived parts, paired to a Ford T5 five-speed and a Ford 8" rear axle on a custom three-link suspension. The build is notable for its subtle body modifications, carefully hidden engine clearance work, and strong attention to safety and handling detail. Biermann passed away shortly after completing the car in 2008, and it is now preserved by The St Louis Car Museum.

Photos
32 pictures collected from the write-up, in the order they were posted, shown from BritishV8: the site for enthusiasts of modified British sports cars. A picture opens larger here, with the way through to the page it is on.
How it was done
Building the heart of the car
The engine began as a Buick 215 aluminum V8, bored, re-sleeved and stroked to just over 308 cubic inches with Buick 300 heads and crankshaft, Chevy rods, Ross pistons and a Crower cam. Rover-sourced ignition parts and a reworked Edelbrock intake with its markings ground off kept the engine's origins understated.
Cooling and exhaust sorted
A Griffin aluminum radiator and pulling electric fan handled cooling. Custom ceramic-coated tri-y headers routed through bellmouthed holes cut in the inner fenders, feeding dual Flowmaster mufflers that exit symmetrically around a re-centered fuel tank.
Driveline upgrades
Power reaches the road through a Ford-spec T5 five-speed gearbox with a heavy-duty Centerforce clutch and a custom driveshaft, into a Ford 8" rear axle fitted with a Currie aluminum gear case, Auburn limited-slip differential and 28-spline shafts.
Suspension and brakes
Up front the stock MGB suspension was retained but stiffened with a larger anti-sway bar. Out back, Biermann engineered a custom three-link setup with Bilstein coilovers and a Panhard rod. Wilwood calipers and rotors at all four corners, with dual residual pressure valves, gave the car strong, controlled stopping.
Reworking the body
Though built on a 1969 shell, the car received a rubber-bumper firewall for clearance, subtle rear quarter panel flares, rolled fender lips, and extensive floor and trunk modifications to fit the new rear suspension. The chassis was reinforced along the floorboards for added stiffness.
Finishing touches
The car was finished in a Mini-sourced white paint closely matching MG's Old English White, with a mesh grille, later-model mirrors and a Stayfast top. Inside, Fiero seats with tan leather, heated seat switches and Schroth four-point harnesses completed a car built as much for safety as for speed.
A finished build, cut short
Ken Biermann completed the MGB V8 in 2008 but became ill soon after and was still sorting out the car when he passed away that August. The car is now kept by The St Louis Car Museum, which supplied photographs so the build could be documented and shared.
A summary in our own words. The full account, with all its detail, is in the original write-up: read it at BritishV8: the site for enthusiasts of modified British sports cars ↗
Worth knowing
- Routing headers through bellmouthed fender holes can improve both clearance and strength.
- A three-link rear suspension needs significant trunk floor and shelf modification to fit properly.
- Dual residual pressure valves help a stock master cylinder work well with aftermarket calipers.
- Subtle fender flares and rolled lips can add tire clearance without changing the car's look.
- Four-point harnesses like Schroth's are worth fitting for genuine safety gains, not just show.
