This Camshaft is good for Drag Racing Engine / TT Engines with High Compression, Porting, Exhaust Pipe, and Bored Carbs. Big Bores / Strokers would work well with this cam (Big Bore / Strokers Highly Recommended for duners and MX bikes using this camshaft.) Porting is Highly Recommended with this camshaft. Aftermarket Valve Springs are required for this cam (KW, Web, or PSI Springs recommended). Larger Followers are highly recommended. Will require shortened or sunk valve guides and may require cam-tower clearance. The 921 Exhaust Lobe VS the 812+5 Exhaust Lobe. The added duration of the 812+5 works well with well scavenging exhaust systems on larger displacement engines.
