335 Grind, Welded Lobe, 224cc
Description
- The 335 has a big duration with lower lift so it can be used in large cubic inch OHV engines where valve to piston clearances are minimal. This cam is very aggressive and 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.
