Edelbrock part #7840 Performer-Link timing chain is 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. Four 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- ? Performer roller chain sets are engineered to operate up to 6500 rpm.- ? Never hammer directly on chain or sprockets. You can crack the hardened links and pins and cause early failures. - ? Use a sleeve for installations that require hammering, a brass drift punch may be used if you carefully alternate blows on either side of the sprocket to avoid cocking. - ? Never stretch the chain with a screwdriver. - ? Check for clearance between the timing chain and block and between the chain and front cover before reassembly. - ? Be sure that both cam and crank sprockets are exactly in line with each other. Misalignment can cause chain to break
