The COMP Cams Hi‑Tech belt drive for Chevrolet Small Block and Oldsmobile Rocket applications is built for extreme use, with an adjustable Vernier sprocket for precise timing and an idler system that reduces belt flap across the rev range. It absorbs crank harmonics, includes a camshaft thrust adjustment without shims, and double lip seals for long life — intended for serious street and race installations.
