Fits 1955-1998. small block Chevrolet V8

Comp Cams "Xtreme Energy Cams" are the latest series of high performance camshafts to take advantage of the newest development of camshaft design and valve train technology. They have an aggressive lobe design that produces better throttle response than other cams with the same duration and they still deliver strong engine vacuum. Comp Cams "Xtreme Energy Cams" can be used for any street or street/strip application where both top end horsepower and good throttle response are desired.

The benefits of swapping the 4 & 7 firing order in both small and big block Chevys is something that smart engine builders understand. Not only are there gains in horsepower to be had with this switch, but you can also realize an exceptionally smooth torque curve.
