Saginaw Metal Casting Operations is an automobile engine foundry plant in Saginaw, Michigan. Opened under GM management in 1919, the factory produces engine blocks and cylinder heads for General Motors vehicles. The factory currently occupies 1.9 million square feet on 490 acres. Historically in September 1927 it was known as the Chevrolet Grey Iron Foundry. In the past when it was called GM-Saginaw Product Company (SPC) a cloverleaf casting symbol mark was cast onto the iron component.[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. The address is 1629 N Washington Ave. Saginaw, MI 48601, and is located on the Saginaw River. Camshafts, connecting rods and other internal engine components are manufactured at Bay City Powertrain. Casting operations were also provided by Massena Castings Plant and Defiance Foundry.
