[1] [2] The location has been the primary source of engine block and cylinder heads for all of GM's engines, to include Oldsmobile, Pontiac, Cadillac, Chevrolet, Buick and GMC for most of the 20th century.
Engine block and cylinder heads were cast at Saginaw Metal Casting Operations, internal engine components were created at Bay City Powertrain and Grand Rapids Operations, and the engines were then assembled at Tonawanda Engine and Romulus Engine.

The early Repco engines produced up to 300 bhp (220 kW), and featured new SOHC cylinder heads and iron cylinder liners. The 1967 and later versions of the Repco engine had proprietary engine blocks. In the mid-1980s, hot rodders discovered the 215 could be stretched to as much as 305 cu in (5 L), using the Buick 300 crankshaft, new cylinder ...
