Cams
Nice horsepower camshaft with approximately .308 lift. Small base circle. Welded and ground.
- The 308 is our most popular grind for modified clone class. This cam is easy on the valve train and has a very wide power band. This cam requires an upgraded spring package, billet rod, and billet flywheel. 308 is the highest you can go with stock rockers.
- The lobes are welded for extra durability, extending the life of this cam.
*Price of 224 Predator is slightly higher.
Note: Block or crankshaft may require clearance to clear camshaft lobes.

308-224
The 224cc camshafts have .550″ main journal sizes. The cams have been clearanced between the lobes and feature narrow lobes. These modifications 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 Harbor Freight Predator 224cc and Tillotson 224cc engines.
