Edelbrock Accu-Drive Gear Drive S/B Ford 65-84

If you're working on a small-block Ford from 1965 to 1984, this Edelbrock Accu-Drive gear drive kit is a solid option for replacing your stock timing chain. It uses a compound gear train to transmit power from the crankshaft to the camshaft, offering more accurate timing control without the stretch you can get from a chain. This can lead to more precise valve timing and smoother engine operation.

The installation is pretty straightforward: you'll swap out the stock crank and camshaft sprockets for the Accu-Drive gears and install the idler assembly. Most applications won't need any block modifications, though you might need to do some minor fitting on the axles and the front cover. A unique feature here is the main idler gear, which floats to find its best position between the crankshaft and camshaft gears. This ensures an even load distribution between them, which is great for longevity and consistent performance. The gears themselves are made from billet SAE-1144 steel with induction-hardened, shaved teeth for precision, and the kit includes hardened and ground idler pins, also from billet steel. It's designed to work with all standard camshafts.
