Edelbrock 7840 - Timing Chain And Gear Set, Buick 400-430-455
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.
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
