Replaces the stock timing chain with a precision gear drive system. The gear drive can be easily installed. The Accu-Drive system transmits power from the crankshaft gear to a full-floating main idler, which drives the camshaft gear. Accu-Drive gear drives are not recommended for use above 7000 rpm or on computer controlled vehicles with knock sensors. Also, not applicable to stock Chevy hydraulic roller lifter cam-equipped engines.
