COMP Cams Belt Drive System Chevy BB

If you're building a serious street performance or race engine for your Chevrolet Big Block, this Hi-Tech Belt Drive System from COMP Cams is a solid choice. It's designed to handle extreme applications with high RPMs and high compression, offering a more precise way to set your engine's timing than traditional timing sets. This system fits a wide range of Chevrolet and GMC trucks and vans from the late 80s through the mid-90s, including models like the Chevrolet C1500, C2500 Suburban, and GMC K2500.

What sets this belt drive apart is its infinitely adjustable Vernier sprocket, which allows for absolute timing accuracy, letting you dial in your cam timing precisely. It also features a unique belt idler system that significantly reduces belt flap, even at high RPMs. This not only helps with consistent performance but also absorbs crankshaft harmonics. By managing these harmonics, the system helps prevent valve train instability that can rob your engine of power and potentially cause damage. The camshaft thrust adjustment system is also unique, allowing for adjustment without the need for shims, and it includes double-lip seals to maintain crankcase vacuum and ensure long life.

This is a comprehensive system built for demanding use. It's a significant upgrade for anyone looking to maximize the performance and reliability of their Chevrolet Big Block engine, especially when pushing the limits on the street or at the track.
