89-7EXP Grind, Flathead Core
- This fast ramp cam was designed to turn a stock unrestricted engine well into the mid to high 6000 RPM range. Excellent top end! We recommend billet lifters and heat treated lower retainers as well as beefing up the tappet bores.
- The lobes are hardened for extra durability, extending the life of this cam.
