356 Grind, Welded Lobe, Clone 13HP
Description
- The 356 is capable of extreme RPMs. With its early valve opening, larger lift and wider duration, it's a proven winner. Upgrading the valve springs, a billet connecting rod, and billet flywheel are mandatory. A carb with a 1.41" or 36mm venture or larger is highly recommended. The use of big valves is also recommended.
- The lobes are welded to increase durability, extending the life of this cam.
