How do I know if my engine has a flat tappet camshaft?

GM gradually introduced roller camshafts starting in the mid-1980s. For many trucks and SUVs, flat tappet cams were used until the mid-1990s. The best way to confirm is to remove the intake manifold or timing cover to visually inspect the camshaft and lifters.

What modifications are recommended for this camshaft?

This camshaft is best suited for modified 350 TPI engines. It pairs well with an improved chip, upgraded injectors, a better plenum, improved runners, and an enhanced exhaust system to maximize its performance potential.

Are there any special considerations for older engines?

Yes, 1955-1957 Chevrolet 265 engines require a specific groove on the 5th cam journal for proper oiling. It is recommended to contact COMP Cams for more detailed information regarding this specific requirement.

It's specifically designed for modified engines with computer-controlled systems, offering an improved chip, injectors, plenum, runners, and exhaust.

This camshaft is built for 1958-1998 262-400 cubic inch Small Block engines that originally came with a flat tappet camshaft. It's important to verify your engine's camshaft type, as GM gradually introduced roller camshafts from the mid-80s onward, especially in performance applications like Camaros, Firebirds, and Corvettes. For example, it fits many Chevrolet trucks and SUVs that retained flat tappet cams into the mid-90s. It's also a good fit for a range of vehicles including the Chevrolet Camaro, Corvette, and Caprice, as well as AM General Hummer models from the 90s.

When installing this camshaft, remember that 1955-1957 Chevrolet 265 engines require a specific oiling groove on the 5th cam journal. Always refer to the manufacturer's installation instructions for complete details and any specific requirements for your application.
