What's in the Box

Info

Replace your timing chain with a Speedway Tru-Gear gear drive. Unlike timing chains, a gear drive doesn't stretch, so your cam timing stays more accurate. We builds these drives with dual idler gears, making them more stable than single idler gear drives. A Tru Gear gear drive is as easy to install as a timing chain and will fit under your stock timing chain cover. Noisy gears give your engine a "supercharged" sound. 

For use on Chevrolet Small Block engines 1957–1995 262-400 c.i. all without “FACTORY” hydraulic roller camshaft.

Yes this will work fine with a Comp camshaft as long as it is the early style and not a later hydraulic roller style which was used in some 1987 and newer small block Chevy engines.
