04-3 IN / 07-3 EX Grind, Flathead Core
- This cam will produce more low end horsepower and maintains the same top end as the 7X. This cam is hard on the block so billet lifters and welding of the exhaust lifter bore is recommended. Excellent cam for all unrestricted classes.
- The lobes are hardened for extra durability, extending the life of this cam.
