MSD Distributor Pro-Billet Cam Sync Signal Mechanical Chevy Big/SB (MSD-2340) 2340

Are you running an aftermarket fuel injection system and looking for a top-notch distributor that actually works? If so, these Pro-Billet Cam Sync Crank Trigger distributors from MSD are just what you need. They're designed to work with EFI management systems that fire the fuel injectors in the same order as the engine's firing order. These systems require a sync signal to know when the number one cylinder is firing. The sync pickup of these distributors is fixed at 45 degrees BTDC on the number one cylinder, and this signal will reliably alert your ECU as to when the number one cylinder is preparing to fire. The distributors are available in a low-profile or small diameter models to help fit where space is tight. Each distributor housing is CNC-machined from billet 6061-T6 aluminum, creating a strong, precise housing. The rotor features thick vanes to stir up the air and is injection-molded from Rynite for high dielectric strength. The base of the low-profile model is also molded out of Rynite and is bolted to the billet aluminum housing. A 0.500 in. polished steel shaft spins the rotor, and is guided by a sealed ball bearing at the top and an extra-long sintered bushing at the bottom for added stability. These distributors are ready to drop in your race engine, from the bronze gear to the brass terminals of the cap. Chevrolet models have an adjustable slip collar that allows you to accurately set the distributor's installation depth in the engine. An MSD crank trigger, ignition control, and MSD 6, 7, 8, or 10 Series ignition must be used.
