COMP Cams Camshaft Kit CS 299T HR-7 BMT

If you're looking to build a serious street/strip machine with a Chevrolet Small Block engine, this COMP Cams Big Mutha' Thumpr camshaft kit is designed to give you a very noticeable idle and aggressive performance. This kit is intended for engines that can handle a substantial camshaft upgrade, requiring at least 9.5:1 compression, a 2800+ RPM stall speed torque converter, and supporting modifications like an upgraded intake, rear gears, and headers to really let it breathe.

This K-Kit is a complete package, meaning it comes with everything you need to swap out your old camshaft and associated valvetrain components. Inside the box, you'll find the CS 299T HR-7 BMT hydraulic roller camshaft itself, along with a full set of lifters, valve springs, retainers, valve locks, and valve stem seals. To ensure proper timing and installation, it also includes a timing chain set and assembly lube. This comprehensive approach helps ensure that all the parts work together harmoniously for improved performance and reliability.

This kit is designed to fit a wide range of Chevrolet GEN 1 Small Block engines, covering displacements from 262ci all the way up to 400ci. It's important to verify your specific engine's factory configuration, as GM transitioned to roller camshafts gradually from the mid-80s onward. This kit is specifically for engines that originally came with a flat tappet camshaft setup. If you're unsure, checking your intake manifold or timing cover will reveal whether you have a factory roller or flat tappet setup. This kit is not compatible with LT1/LT4 engines or LS-based engines.
