If you're looking to upgrade your big-block Chevy engine, the Edelbrock part #7891 Accu-Drive Camshaft Gear Drive Kit is the perfect solution. This innovative kit replaces your stock timing chain with a state-of-the-art gear drive system that uses a compound gear drive train, ensuring a reliable and precise operation.
Installing the Accu-Drive kit is a breeze! Simply swap out the stock crank and camshaft sprockets with the included Accu-Drive gears, and slide in the idler assembly. Most installations won’t require any modifications to your engine block, although you might need to make minor adjustments to the axles and front cover.
This gear drive system efficiently transmits power from the crankshaft gear to a full-floating main idler, which in turn drives the camshaft gear. One of the standout features of the Edelbrock Accu-Drive system is its unique floating main idler gear. This allows it to position itself optimally between the crankshaft and camshaft gears, guaranteeing equal load sharing for smooth operation.
The gears are crafted from high-quality billet SAE-1144 steel, featuring induction-hardened teeth for durability. Plus, the gear teeth are meticulously shaved for precision performance. The kit also includes hardened and ground idler pins made from billet steel, ensuring compatibility with all standard camshafts.
Upgrade your engine with the Edelbrock part #7891 Accu-Drive Camshaft Gear Drive Kit and experience the difference in performance and reliability!
