Chevrolet Big Block Accu-Drive Gear Drive by Edelbrock®

Accu-Drive replaces the timing chain with a full-floating idler gear system for Chevrolet Big Block.

Edelbrock® Accu-Drive gear drive replaces the conventional timing chain on Chevrolet Big Block applications. Power transfers from the crankshaft gear through a full-floating main idler to the camshaft gear. Edelbrock® does not recommend Accu-Drive above 7000 rpm or on computer-controlled vehicles using knock sensors.

• Chevrolet Big Block application • Full-floating main idler gear • Direct gear-drive timing system • 7000-rpm recommended maximum • Not recommended with knock sensors
