How to Install a Cloyes Double Roller on an LT1

The Cloyes Double Roller is an aftermarket timing belt set. These heavy-duty double-roller timing chain sets feature 0.2-inch-diameter rollers, cast iron cam sprockets, and heat-treated steel crank sprockets with triple keyways. The LT1 is a stock small-block engine manufactured by General Motors. It was used in several vehicles from 1992 to 1996, including the Pontiac Firebird, the Chevy Camaro and the Chevy Caprice. Installing this timing chain system will take several hours.
