Product Details

If you're building a large displacement AMC V8, like the 360 or bigger, and you're aiming for serious performance with a high-stall torque converter and a healthy compression ratio, this COMP Cams A8 300B-8 camshaft is a solid option. This camshaft is designed to work best in engines around 360 cubic inches and up, especially when paired with a torque converter rated for 5000 RPM or a robust 4-speed transmission. It also requires an 11.0:1 compression ratio to really wake up.

This camshaft features a race-oriented grind with a 265/276 degree intake/exhaust duration at .050 inch lift, which means it's built for high-RPM power. The solid lifter design means you'll need to be comfortable with more frequent valve adjustments compared to hydraulic lifters, but it allows for more aggressive valve events and higher lift profiles. COMP Cams is a well-known name in performance camshafts, and this part is built to handle the demands of a performance build.

This camshaft fits a wide range of AMC V8 engines, including those found in vehicles like the Jeep CJ series, Jeep Cherokee, and various American Motors models such as the Ambassador and Matador. Make sure your engine build supports the compression and converter requirements for this camshaft to achieve its full potential.
