The COMP Cams Hi‑Tech belt drive for Chevrolet Big Block engines is a complete timing system for extreme, high‑rpm and high‑compression applications. It reduces belt flap across the rev range and absorbs crankshaft harmonics to help prevent valve‑train instability while delivering precise cam timing control. The kit uses an infinitely adjustable Vernier sprocket, a unique idler arrangement, cam thrust adjustment without shims and double‑lip seals for long service life.
