310 Grind, Welded Lobe, 224cc

Description

• The 310 is a monster camshaft with low lift. This cam has all the duration of our bigger cams, but with .310" lift so ratio rockers can be used in OHV modified applications. This cam requires an upgraded spring package, billet rod, and billet flywheel.
• The Lobes on this Cam are Welded.

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.
