Camshaft, Dyno Cams 356, GX390 and 13/15hp OHV - N2

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 33mm Carb or larger is highly recommended along with a 40mm intake valve.
Dual springs required.
The lobes are welded to increase durability, extending the life of this cam.
