General Motors camshaft part numbers are available from Comp Cams, Nasty Z28 and Kendrick Auto. Comp Cams provides the most comprehensive list of part numbers, along with a searchable database.
Comp Cams users who already know the camshaft’s part number or grind number can search for its specifications, whereas users who don't have the part number may choose a manufacturer and engine type from a drop-down menu. Nasty Z28 and Kendrick Auto provide lists of camshaft part numbers that only cover small-block Chevrolet engines. The lists include the engine type and size to help users find the correct part number.
