Edelbrock Accu‑Drive camshaft gear drive kit for Pontiac 326–455 V8 engines replaces a stock timing chain with a precision compound gear train to improve timing control. The floating main idler finds an optimal position between crank and cam gears to equalize load. Gears are billet SAE‑1144 steel with induction‑hardened, shaved teeth and hardened idler pins. The set is compatible with standard camshafts and enables smooth cam rotation and multiple timing adjustments.
