MSD Pro-Billet Ready-To-Run EFI Distributor Chevy 5.0 5.7 7.4L (MSD-8366) 8366

MSD Pro-Billet Ready-to-Run EFI distributors are the perfect upgrade when you start making serious power with your EFI Ford or Chevy. They use a stock-style trigger pickup and come with plug-in connectors. Installation is simple by removing the stock distributor, then plugging in and bolting the new one in place! A maintenance-free magnetic pickup accurately triggers this ignition with increased output from the amplifier, easily outperforming stock ignitions. These distributors will smooth out the engine's idle, improve starting, and perform at a much higher rpm. Their housings are machined from billet aluminum, using state-of-the-art CNC mills and lathes. For stability and endurance, an oversized steel shaft spins in a top-mounted sealed ball bearing for accuracy through the entire rpm range. Chevy models also feature an extra-long sintered bushing at the bottom and an extra oil tract machined into the bottom of the housing for improved lubrication. The tract delivers oil directly to the cam and distributor gears. All of the shafts receive a QPQ coating for low friction wear, and resistance against corrosion from humidity and ozone buildup. The Chevrolet models have also been tested by the Underwriter's Laboratory, and are certified to meet or exceed safety standards for marine ignition systems as set by the U.S. Coast Guard.
