Comp Cams 12-690-47 Oval Track Mechanical Flat Tappet Camshaft
Fits 1955-1998, small block Chevrolet V8s
with 4 & 7 swap firing order.

The oval track line of camshafts from Comp Cams is computer designed for use in high performance racing applications where the top concern is performance potential at higher rpm. This camshaft is more aggressive and requires periodic valve lash adjustment. It is not intended for street use.

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.
