98-3 Grind, Flathead Core

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

• The 98-3 is a good all-around cam for the stock and super stock classes. It also works well on road courses. This cam is easy on the valve train and the tappet bores.
• The lobes are hardened for extra durability, extending the life of this cam.
