MSD 85141 Distributor

Compatible with Small and Big Block Chevy®. This product is not created or sold by Chevrolet®. MSD's cam sync plugs install in place of a traditional distributor to drive the oil pump and provide a cam sync signal when running a Holley EFI, or other aftermarket sequential EFI system requiring a cam sync signal.;

MSD's cam sync plugs are the perfect solution when running an aftermarket sequential EFI system with coil-per-cylinder ignition. The cam sync plug installs in place of a traditional distributor, providing a hall-effect cam sync signal needed for the EFI system to reference the # 1 cylinder. For wet sump applications, the plug also drives the oil pump. MSD's cam syncs are plug and play with Holley EFI systems and can easily interface with most aftermarket EFI systems.;
