Product Details

If you're building a high-performance street or strip Pontiac V8, this COMP Cams Mutha' Thumpr camshaft is a popular choice for getting that aggressive sound and feel. It's designed to work with Pontiac engines ranging from 265 to 455 cubic inches, covering a wide array of classic models. This camshaft is known for its distinct, rough idle that lets everyone know you mean business.

This is a hydraulic flat tappet camshaft, meaning it uses a simple and well-understood valvetrain design. For this cam to perform its best and deliver that street/strip power, you'll want to pair it with at least 9:1 compression, a torque converter with a 2500+ RPM stall speed, an upgraded intake manifold, and performance headers. These components work together to help the cam breathe and make power effectively.

When installing this camshaft, remember that it's intended for performance applications and will produce a rough idle. It's a solid option for enthusiasts looking to give their Pontiac a significant performance boost and a signature sound.
