The 308 is our most popular grind for modified classes.
Easy on the valve train and has a very wide power band.
Requires an upgradeed spring package, billet rod, and billet flywheel.
The lobes are welded for extra durability, extending the life of this cam.
The 224cc camshafts have .550" main journal size. The cams have been clearanced between the lobes and feature narrow lobes. These modification allow for rod clearance due to the 58mm stroke. The compression release is also thinner to clear the 58mm crank counter weight. These camshafts work with Predator 224, Wildcat 223 and Tillotson 236-263cc engines with 58mm crankshafts.
