    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.

    Since founder Vic Edelbrock Sr. began building performance intake manifolds in 1938, Edelbrock has grown into one of the most trusted names in American high-performance parts, from carburetors and intake manifolds to cylinder heads, crate engines, and EFI systems. JEGS has spent decades supplying Edelbrock components to racers, engine builders, and street enthusiasts, backing this extensive lineup with in-house technical support, fast shipping, and a Price Match Guarantee so you can choose proven Edelbrock parts with confidence.

    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.
