Chevrolet Small Block Commander 950 MPFI Systems

Commander 950 Multi–Point Fuel Injection Systems are designed to convert carbureted, non–emission, non–computerized Chevrolet Small Block engines to modern, fully programmable Multi–Point fuel injection. These are complete systems that are engineered to provide all the components and hardware needed for your custom installation. The aluminum intake manifold, billet aluminum throttle body, billet fuel rails, fuel Injectors and related miscellaneous parts are partially assembled and tested prior to packaging. Holley takes this extra step in quality assurance to verify the performance, quality and integrity of the system. With the addition of Commander 950 electronics, Holley multi–point fuel Injection systems offer more features, performance, greater system tunability and outright good looks. That translates to the best value on the market today. Whether your engine is stock, crate or custom–built, a Holley Commander 950 Multi–Point fuel Injection system can help maximize it's performance and make your driving a lot more enjoyable.
