Performer-Link timing chain sets are for use with Edelbrock or stock cams. They have a solid-bushing chain for a true bearing surface that rolls with the sprockets, eliminating chain stretch. Cam sprockets are made from 35,000 psi tensile strength cast iron. Crank sprockets are made from billet SAE-1144 steel and induction heat treated. Three Performer-Link sets are stock replacement parts and 50-state legal (see listings in bold type). All other sets have three keyway setting points to ensure accurate timing selection for early or late-model vehicles. Performer-Link timing sets are not for use above 6500 rpm.
