Additional Application Notes
• In 1987, GM began using hydraulic roller camshafts in Chevrolet Small Block V8's. Before ordering this camshaft, verify that your engine has a flat tappet camshaft. If your engine features a roller camshaft, look at our "08-" camshafts or "07-" camshafts if equipped with an LT1/LT4.
