To complete our short-block, we installed COMP Cam’s Ultimate Adjustable Timing set. The COMP two-piece billet steel cam sprockets allow cam timing changes without removing the degree wheel or releasing the valvetrain load. Timing can be varied from 6 degrees retarded to 6 degrees advanced, and there are no cam bushings to break either. The chain is also a heavy-duty, double-row type with large 0.250-inch rollers and the kit even includes the roller thrust bearing with custom adjusting tool. For our setup, Mulvey installed the camshaft straight up. With 4 degrees already degreed into the cam from COMP, which put our intake centerline at 106 degrees.
