Holley is pleased to announce the release of MSD Pro-Billet Front Drive Distributors. Developed for both Big Block and Small Block Chevys, they're perfect for race engines that need a cam-sync signal for EFI systems but don't have room for a standard distributor because of inadequate firewall clearance or bulky intake setups. MSD Pro-Billet Front Drive Distributors feature an adjustable Hall Effect sync pickup with a built-in LED for easy adjustments, an extra-wide 9mm belt driven by a pulley on the camshaft, and a band-clamp mount for fast, easy rotor-phasing. They come complete with a billet-aluminum bracket and lower housing, a billet distributor head, and a new gear for the camshaft.
