    Chevy Gear Drives

    Accu-Drive® Notes:
    On some late-model engine blocks, it will be necessary to check clearance behind cam gear at the engine block at the 12 o'clock position. Make sure gear clears oil galley bosses on block when in the most rearward position. Grind or machine block for clearance. Clean block before assembling. Not applicable to stock Chevy hydraulic roller-lifter cam-equipped engines.

    Edelbrock 7890 - Edelbrock Accu-Drive Timing Gear Drive

    The Accu-Drive camshaft gear drive kit replaces a stock timing chain with a precision gear drive system. Gear drives are easily installed - Just replace the stock crank and camshaft sprockets with Accu-Drive gears and slip in the idler assembly. The Accu-Drive gear drive system transmits power from the crankshaft gear to a full floating main idler which drives the camshaft gear. The unique feature of the Edelbrock Accu-Drive system is the ability of the main idler gear to float to an optimum position between the crankshaft and camshaft gears assuring absolutely equal load sharing between the crankshaft and the camshaft gears.

    Important Note: Accu-Drive Gear Drives are not recommended for use above 7,000 rpm or on computer-controlled vehicles with knock sensors.
