Edelbrock part #7880 Victor-Link timing chain is a timing chain and gear set is designed for high-performance's street and competition small-block Chevys operating in the 6500-8500 rpm range. #7880 withstands a higher operating range than other timing chains due to the machined link holes and high-strength steel. In addition, the chain links and pins are cold-hardened for greater strength and durability. Nine keyway setting points ensure precise timing selection. Gears are machined from SAE-1144 stress proof steel, have a larger tooth contact area and are induction hardened.- ? 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
