- The 128 is recommended for a .563" stroke, 3+ inch bore. It is for the racers who want a 500+ lift range in an Open or Junior Dragster. This cam is hard on the valve train.
- The alloy billet core is not brittle like the tool steel billet core which allows for the core to be modified for rod clearance. The lobes are welded to increase durability, and extend the life of the cam. Standard core length(4.480") fits most aftermarket blocks utilizing this core length.
- The two piece design allows you to advance or retard the cam to meet your application needs.
