Product Details

COMP Cams is well-known for making performance camshafts, and this Big Mutha' Thumpr hydraulic flat camshaft and lifter kit is a prime example of their work. This kit, part number CL92-602-5, is designed for Buick 350 engines and is intended for street/strip applications. If you're building a performance engine that needs a serious camshaft, this is a solid option to consider.

This kit includes the camshaft itself, a set of lifters, assembly lube to get everything started right, and decals. To get the most out of this camshaft, COMP Cams recommends a minimum of 9.5:1 compression, a 2800+ RPM stall speed torque converter if you have an automatic transmission, and you'll definitely want to pair it with a good intake, rear gears, and headers. Be aware that this camshaft is designed to produce a very rough idle, which is characteristic of aggressive performance cams and part of what makes it suitable for performance builds.

This kit fits a range of Buick vehicles from the late 60s through the early 80s, including models like the Buick GS 350, Skylark, and LeSabre, as well as the Chevrolet Nova. It's important to note that this kit is not CARB approved and cannot be shipped to California. Always refer to the included instructions for proper installation and break-in procedures.
