All our cams from stage 3 and up are brand new cast billets and no return core is required.

TAPPETS: We recommend only COLT CAMS CUSTOM 1.3 diameter max crown lifters = $110.00 US a set.

RETAINER: All our cams are drilled and tapped to accept our custom retainer to keep the gear from walking off. This is not required but highly recommended - $59.00 US

STOCK CAMS: We do carry brand new stock cams as well - $250.00 US

**NOTE!!!!! When we say our camshaft is a straight drop in, we mean: In almost all cases.
However, due to many contributing variances in an engine: heads planed, block decked, valve recession etc... any cam including stock, should always be checked for clearance before start up!
