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.
0.356'' valve lift, 254 degrees duration @ .050''.
