Installation

The Accu-Drive gear drive system transmits power from the crankshaft gear to a full floating main idler which drives the camshaft gear. A 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. The gears are made from billet SAE-1144 steel with induction hardened teeth. Gear teeth are shaved for precision operation. The set features hardened and ground idler pins from billet steel and are compatible with all standard camshafts

Edelbrock® Corporation has seven locations: four in Torrance and three in San Jacinto, California, totaling to over 500,000 square feet. Torrance headquarters include R&D, manufacturing, state-of-the-art testing facilities, advertising, and tech support. The company's Aluminum Foundries are located close by in San Jacinto. In 2008, they added a new Permanent Mold and Heat Treat facility next to the existing sand cast foundry, which has been called "the most state-of-the-art sand cast foundry west of the Mississippi." This investment in American facilities is part of Edelbrock's commitment to "Made in USA" products and performance.
