Product Details

If you're looking to get more grunt out of your Oldsmobile V8, this COMP Cams Xtreme Energy camshaft kit is a solid option. Designed for engines like the 260, 307, 350, 403, 400, 425, and 455, this kit aims to improve torque through the low end and into the mid-range, while still maintaining a good, manageable idle. It's a popular choice for drivers who want a noticeable improvement in pulling power without making the engine sound too radical.

This kit comes with everything you need to get the job done: the camshaft itself, a set of lifters, a new timing chain set, assembly lube, decals, and instructions. The camshaft features a 212/218 degree duration with High-Flow Technology (HFT) lobes, which help it breathe better and contribute to that improved torque curve. It's well-built and designed to be a direct fit for a wide range of Oldsmobile, Buick, Cadillac, and Chevrolet vehicles from the mid-60s through the early 90s.

When installing a new camshaft, it's always a good idea to refer to the included instructions for the proper break-in procedure. This ensures the camshaft and lifters seat correctly and last for a long time. This kit is a great way to wake up an older V8 and give it a more responsive feel.
