Product Details

This COMP Cams kit gives you everything you need to swap in a new camshaft and lifters for your Pontiac V8. Inside the box, you'll find the XE256H-10 camshaft itself, a set of matching hydraulic lifters, assembly lube to get everything started right, and decals for your engine bay. This kit is designed to fit a wide range of Pontiac, Buick, and Oldsmobile V8 engines from the late 50s through the early 80s, including popular models like the Firebird, Grand Prix, and LeMans.

The XE256H-10 camshaft is part of COMP Cams' Xtreme Energy line, focusing on delivering strong torque right from the low end and through the mid-range. This means you'll feel a noticeable improvement in acceleration from a stop and when passing. It's also designed to maintain a good, manageable idle, making it a solid choice for street-driven vehicles that see a lot of daily use. The hydraulic flat tappet design means it works with your existing valvetrain components, simplifying installation.

When installing a camshaft, it's crucial to follow the included instructions carefully, especially regarding the assembly lube and initial break-in procedure. This kit is a well-built option for anyone looking to improve the low-end grunt and overall responsiveness of their classic Pontiac V8.
