{"product_id":"pro-flo-4-efi-kit-sbc-vortec-550-hp","title":"Fuel Injection System","description":"The Edelbrock Pro-Flo 4 EFI Kit #35780 for Small-Block Chevy engines with Vortec\/E-Tec cylinder heads 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-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 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. The manifold is also 0.75 inch taller than the standard LS3 version to promote smoother airflow into the rectangular-port heads. This kit uses 29 lb\/hr injectors and is rated for 450 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 application's initial programming. Once provided with basic information such as type of engine, cubic inches, firing order, and cam profile, the E-Tuner App then selects the most appropriate base calibration. Once the base calibration is set, the self-learning E-Tuner App takes over to continually maximize the fuel map for your specific engine configuration, even compensating for changes in altitude and weather. The E-Tuner App 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. The exclusive Edelbrock E-Tuner 4 app is Free and Available for Android and IOS based smart phone or tablet.","brand":"Edelbrock","offers":[{"title":"Default Title","offer_id":48212137574648,"sku":"BDVJ_35780","price":2500.95,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0725\/1538\/7640\/files\/EDE35780.jpg?v=1775683853","url":"https:\/\/nadersautosupply.com\/products\/pro-flo-4-efi-kit-sbc-vortec-550-hp","provider":"Nader's Auto Supply","version":"1.0","type":"link"}
