COMP Cams Belt Drive Chevy SB W/Idler W

If you're building a high-performance Small Block Chevy for serious street use or the race track, getting your timing dialed in precisely is critical. This COMP Cams Hi-Tech Belt Drive system is designed to give you absolute accuracy and durability, even in extreme conditions. It fits a wide range of Chevrolet and Pontiac vehicles from the late 80s and early 90s, including models like the Camaro, Corvette, and Firebird.

What sets this system apart is its infinitely adjustable Vernier sprocket, allowing for precise camshaft timing adjustments without guesswork. The unique belt idler system is engineered to significantly reduce belt flap across the entire RPM range, which helps maintain consistent timing and prevents instability. Furthermore, this belt drive is built to absorb crankshaft harmonics, protecting your valve train from performance-robbing vibrations and ensuring it stays stable and efficient. It also features a unique camshaft thrust adjustment system that doesn't require shims, simplifying installation and maintenance. The inclusion of double-lip seals is a thoughtful touch, designed for long life and to help maintain maximum crankcase vacuum.

This is a well-built system for demanding applications where reliability and accuracy are paramount. It's a substantial upgrade for anyone looking to maximize the performance and longevity of their Small Block Chevy engine.
