# Edelbrock 70-91 AMC 304/360/390/401 Pro Flo 4 4150-Style 35lb/hr Fuel Injection Kit The Edelbrock Pro-Flo 4 EFI Kit #35650 for 1970-1991 AMC 304, 360, 390, 401 CID engines is a fully sequential multi-port injection system designed with a fuel injector strategically positioned in each runner of the intake manifold to deliver the best fuel atomization and most even distribution to each cylinder. This system features the high-performance Victor Jr.-style single-plane intake manifold that comes preassembled with high-flow injectors, fuel rails and 4150-flange throttle body. All supporting sensors are included along with distributor, wire harnesses and ECU. The Victor manifold is designed with a larger cross-sectional area in the plenum and larger runners for high-horsepower and/or large cubic-inch applications. This kit uses 35 lb/hr injectors and is rated for 550 horsepower at 58 PSI of fuel pressure. Calibration of the Pro-Flo 4 is a simple process with a Setup Wizard providing guidance through the E-Tuner's initial programming. Once provided with basic information such as type of engine, cubic inches, firing order, and cam profile, the E-Tuner then selects the most appropriate base calibration. Once the base calibration is set, the self-learning E-Tuner takes over to continually maximize the fuel map for your specific engine configuration, even compensating for changes in altitude and weather. The E-Tuner provides more advanced tuning options that allow precise control over cold starts and acceleration while retaining the simplicity that Pro-Flo systems are known for. No laptop tuning is required.The exclusive Edelbrock E-Tuner 4 app is Free and Available for Android and IOS based smart phone or tablet. - New ECU Preloaded w/80 Dyno-Tuned Calibrations This Part Fits: Year Make Model Submodel 1970 American Motors Ambassador Base 1971-1974 American Motors Ambassador Brougham 1970-1971 American Motors Ambassador DPL 1970-1972 American Motors Ambassador SST 1970,1978-1979 American Motors AMX Base 1978-1979 American Motors Concord Base 1979 American Motors Concord DL 1979 American Motors Concord Limited 1972-1976 American Motors Gremlin Base 1976 American Motors Gremlin Custom 1977 American Motors Hornet AMX 1970-1971,1973-1977 American Motors Hornet Base 1971 American Motors Hornet SC/360 1971-1977 American Motors Hornet Sportabout 1970-1972 American Motors Hornet SST 1971-1974 American Motors Javelin AMX 1970-1974 American Motors Javelin Base 1970-1972 American Motors Javelin SST 1970 American Motors Javelin SST Mark Donohue 1970 American Motors Javelin SST Trans Am 1971-1978 American Motors Matador Base 1974 American Motors Matador Brougham 1974 American Motors Matador X 1978 American Motors Pacer Base 1979 American Motors Pacer DL 1979 American Motors Pacer Limited 1970 American Motors Rebel Base 1970 American Motors Rebel SST 1970 American Motors Rebel The Machine 1979 American Motors Spirit Base ## Details - **Price:** 3454.06 CAD - **Vendor:** Edelbrock - **Type:** Fuel Injectors - Single ## Variants | Variant | Price | Available | |---------|-------|-----------| | Default Title | 3454.06 CAD | In stock | ## Images - Photo - Primary - User 1 --- > Source: [Standard Auto Part](https://www.standardautopart.com/products/edelbrock-70-91-amc-304-360-390-401-pro-flo-4-4150-style-35lb-hr-fuel-injection-kit) > Updated: 2026-06-27
