1980 MG MGB with a 3.4 L V6

Brian McCullough owner of BMC British Automobile in Isanti, Minnesota sent us details about one of their newest conversions. You might remember their previous MGB we featured. This project started with a 1980 MG MGB that received a 3.4 L L32 V6 and five-speed manual transmission. The engine’s output was increased to 215 hp and 254 lb-ft of torque over the factory rating of 160 hp and 200 lb-ft of torque. This was accomplished keeping the original 9:1 compression ratio by using an upgraded camshaft and some work on the factory iron heads. BMC also lowered the suspension and installed traction bars to keep the rear axle in place under acceleration.

    GM’s 60 degree V6 is the perfect swap for these MGB’s. Real shame other swap candidate’s pass over the 60 degree in it’s various forms. Such a versatile engine family.
