Product Details

COMP Cams is well-known for performance camshafts and valvetrain components. This Xtreme Energy hydraulic flat tappet camshaft and lifter kit is designed for Oldsmobile V8 engines from 260 to 455 cubic inches, fitting a wide range of GM vehicles from 1967 and newer. If you're looking to wake up your engine for street or strip use, this kit offers a significant performance upgrade over stock.

This kit includes the camshaft, lifters, assembly lube, decals, and instructions, so you have the essential parts to get started. It's built for applications needing at least 9:1 compression, and you'll want to pair it with headers, gears, and a higher stall torque converter (around 2800+ RPM) to really take advantage of its aggressive profile. Expect a noticeable change in your engine's powerband and a rougher idle, which is characteristic of these performance cams.

For optimal performance and longevity, ensure your engine meets the compression and supporting modifications requirements. This kit is a solid option for enthusiasts looking to extract more power from their classic Oldsmobile or related GM V8.
