COMP Cams Camshaft OL 252H-10

This is the COMP Cams High Energy camshaft, part number 42-227-4. It's a hydraulic flat tappet camshaft designed to give your Oldsmobile V8 engine a boost in low-end torque and improve fuel economy, all while maintaining a smooth idle. This makes it a solid choice for daily drivers and family sedans that need a bit more grunt off the line without sacrificing everyday drivability. It fits a wide range of Oldsmobile engines from 260 to 455 cubic inches, as well as many Buick, Cadillac, and Chevrolet models from the late 60s through the early 90s.

The High Energy series camshafts are well-known for their ability to provide noticeable improvements in the lower RPM range, which is exactly where you'll feel it most when accelerating from a stop or cruising around town. The 206 degrees of intake and exhaust duration at 0.050 inch lift are carefully chosen to work well with stock cylinder heads and intake manifolds, making installation more straightforward. You'll get a more responsive feel from your engine without needing to rev it excessively, contributing to better gas mileage on your commute.

When installing a camshaft like this, it's always a good idea to have a fresh set of lifters and a proper break-in oil on hand. Following the manufacturer's recommended break-in procedure is crucial for ensuring the longevity of the camshaft and lifters. This camshaft is designed to be a direct replacement for your stock unit, fitting right into place with the correct installation procedures.
