Product Details

If you're building a pro street or bracket racing Oldsmobile with a 260 to 455 V8, this COMP Cams Xtreme Energy camshaft is a solid option. It's designed to work with a good intake manifold, headers, and appropriate gearing, plus a torque converter with a stall speed of 3200 RPM or higher to really let this cam shine.

This hydraulic flat tappet camshaft features a 250/256 degree duration split, meaning the intake and exhaust valves open and close for different lengths of time. This profile is well-suited for maximizing power in performance-oriented applications like bracket racing where consistent performance is key. The well-built nature of COMP Cams products means you can expect reliable operation when properly installed and maintained.

This camshaft fits a wide range of Oldsmobile V8 engines from 1967 and up, including popular models like the Cutlass Supreme and Delta 88, as well as many Buick and Cadillac V8 applications from the mid-70s through the late 80s. Make sure to check the full fitment list to confirm it works with your specific vehicle.
