Product Details

COMP Cams is a well-known name for folks looking to get more out of their engines, and this Mutha' Thumpr camshaft is a prime example of their performance focus. This particular camshaft, part number 92-601-5, is built for Buick 350 engines and is designed for street and strip applications. It's a hydraulic flat tappet design, meaning it uses hydraulic lifters to maintain zero valve lash automatically, simplifying setup compared to solid lifter cams.

To get the most out of this camshaft, you'll want to ensure your engine is set up for it. COMP Cams recommends at least 9:1 compression, a 2500 RPM or higher stall speed torque converter if you have an automatic transmission, and that you're running an aftermarket intake, headers, and appropriate gearing. Expect a noticeable, rough idle that lets everyone know you've got a serious performance cam under the hood. This camshaft fits a wide range of Buick models from the late 60s through the early 80s, including popular choices like the Skylark, LeSabre, and GS models, as well as some Chevrolet Malibu and Pontiac Catalina applications.
