Edelbrock 7892 Accu-Drive Gear Drive

The Edelbrock ACC-Drive Camshaft Gear Drive replaces a stock timing chain with a precision gear drive system. The gear drive can be easily installed by replacing the stock crank and camshaft sprockets with ACC-Drive gears and slip in the idler assembly. The ACC-Drive gear drive system transmits power from the crankshaft gear to a full floating main idler which drives the camshaft gear. A unique feature is the ability of the main idler gear to float to an optimum position between the crankshaft and camshaft gears, assuring equal load sharing between the crankshaft and the camshaft gears. They provide up to eight degrees of cam-timing adjustment in two-degree increments and have offset bushings for easy cam indexing, as well as SAE 8620 steel gears that will operate at higher RPMs. The ACC-Drive Gear Drives are not recommended for use above 7, 000 RPM or on computer-controlled vehicles with knock sensors. They have smooth cam rotation and multiple cam timing settings.
