Installation Notes

Verify the engine’s crankshaft-to-camshaft center distance before installation; the listed fitment notes specify a standard 4.521" center distance for street billet standard-duty engine applications. Confirm the engine family and timing cover clearance before assembly. Use proper timing marks and degreeing procedures when setting cam timing, especially when taking advantage of the adjustable keyways.
