As of July 30th, 2019, 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 cam features a softer intake opening which allows you to run less spring pressure thus improving acceleration. The exhaust lobe closes extremely late increasing HP on top end without sacrificing bottom end. Welding of the EX tappet bore is still recommended.
- The lobes are hardened for extra durability, extending the life of this cam.
