This is Edelbrock's carbureted intake manifold kit for the GM LS1 V-8. Edelbrock LS1 intake manifolds allow the user to retrofit any Gen III-based small-block into a classic vehicle, using a carburetor. The kit includes an easy-to-install Electric Timing Control Module, which picks up manifold air pressure, crank position, and cam position signals to control the coil-on-plug ignition system with proper timing.
