DynoCams will no longer be able to provide flathead cast cores for stock or hot stock grinds. These cast cores have not been produced by Briggs and Stratton for many years and there is no secondary supplier. We will, however, still grind stock profiles if you can provide a cast core meeting the following criteria:
Cam journals free of rust, damage, or excessive wear
Cam gear is free of rust, damage, or excessive wear
-
The intake and exhaust base circles are no less than .725
Description
- 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.
