This timing chain and gear set is designed for high-performance street and competition small-block Chevys operating in the 6500-8500 rpm range. The chain set can withstand 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 SAE1144 stressproof steel, have a larger tooth contact area and are induction hardened.
