DYNO356-390 CAM
The 356 is capable of extreme RPM's. With its early valve opening, larger lift, and wider duration, it's a proven winner. The lobes are welded to increase durability, extending the life of this cam. Upgrading the valve springs, a billet connecting rod, and billet flywheel is mandatory. A 33mm carb or larger is highly recommended along with a 40mm intake valve. Dual springs required.
