What is the intended use for this COMP Cams camshaft kit?

This camshaft kit is designed for high-performance street and strip applications. It's built to deliver significant power gains, especially at higher RPMs, and is intended for enthusiasts looking to build a more aggressive engine.

What supporting modifications are recommended for this camshaft?

COMP Cams recommends a minimum of 9.0:1 compression, a torque converter with at least a 2500 RPM stall speed, an upgraded intake manifold, proper gearing, and headers to maximize the performance of this camshaft.

Will this camshaft fit my 1990 Chevrolet 350 engine?

This kit fits Chevrolet Gen 1 Small Blocks, but it does not fit factory roller Small Blocks built from 1985 and newer. Many 1990 350 engines came with roller cams, so you will need to remove the intake or timing cover to confirm if your block has a factory roller or a flat tappet camshaft.

Product Details

If you're looking to build a serious street/strip machine with a Chevrolet Gen 1 Small Block, this COMP Cams Mutha' Thumpr camshaft kit is a solid option. This kit centers around the CS 291T HR-107 M hydraulic roller camshaft, designed for engines that need to breathe deep and make power at higher RPMs. It's built for performance applications, so expect a noticeable, rough idle that lets everyone know this engine means business.

To get the most out of this camshaft, COMP Cams recommends a minimum of 9.0:1 compression, a torque converter with at least a 2500 RPM stall speed, and supporting modifications like an upgraded intake manifold, proper gearing, and headers. This kit includes the camshaft and all the necessary components to ensure a complete and correct installation, making it a convenient choice for your build. It's important to verify your specific engine block is a flat tappet design, as this cam is not compatible with factory roller blocks from 1985 and newer, or any LS-based engines.

This kit is intended for performance enthusiasts who understand the requirements for a high-performance camshaft. It's a well-built component that, when paired with the right supporting parts and tuning, will significantly change your engine's powerband. Remember to consult your vehicle's service manual or physically inspect your engine to confirm the camshaft type before ordering.
