COMP Cams Camshaft CS Replacement For 3

If you're looking to wake up the performance of your Chevrolet Small Block engine, this COMP Cams Factory Muscle camshaft is a solid option. This is a solid flat tappet camshaft designed for engines like the 302 Z28, 327, and 350 LT1, offering a factory performance profile that's well-known for its powerband.

This camshaft features a 254 degrees of intake duration and 254 degrees of exhaust duration at .050 lift, with a .495 inch lift on both intake and exhaust. It's built to replace factory camshafts like the GM 3849346, providing an improved performance feel without going too radical for street use. It's designed for Chevrolet Small Block Gen 1 engines, covering a wide range of displacements from 262ci up to 400ci, but it's important to confirm your engine uses a flat tappet system and not a factory roller setup, especially on later models.

When installing this camshaft, remember that it requires a proper break-in procedure to ensure the flat tappet lobes and lifters seat correctly. You'll also want to ensure your valve springs are up to the task of handling the lift. This camshaft is a popular choice for those rebuilding or modifying classic Chevrolet engines where a noticeable performance increase is desired.
