Edelbrock Accu‑Drive cam gear drive kit for small‑block Ford engines replaces the stock timing chain with a precision compound gear train for more accurate timing control. The system transmits crank power to a floating main idler that shares load evenly between crank and cam gears. Gears are billet SAE‑1144 steel with induction‑hardened, shaved teeth; hardened and ground idler pins provide durability. Installation typically replaces sprockets and installs the idler assembly with minimal block modification.
