Product Details

Edelbrock is well-known for performance parts, especially their intake manifolds and carburetors. This Pro-Flo 4 EFI kit builds on that legacy, offering a complete electronic fuel injection system for your AMC V8 engine. If you're looking to upgrade your 1970-1991 AMC 304, 360, 390, or 401 cubic inch engine, this kit brings modern fuel delivery technology to a classic platform. It's designed to provide better fuel atomization and more even distribution to each cylinder compared to a carburetor setup.

This kit features a high-performance Victor Jr.-style single-plane intake manifold, which Edelbrock designed with larger plenums and runners to support high-horsepower and larger displacement engines. It comes pre-assembled with high-flow 35 lb/hr fuel injectors, fuel rails, and a 4150-flange throttle body. The system is a fully sequential multi-port injection setup, meaning each cylinder gets its own precisely timed fuel pulse. This kit is rated to support up to 550 horsepower at 58 PSI of fuel pressure and is compatible with factory-style cylinder heads or Edelbrock Performer and Performer RPM cylinder heads. It also includes a distributor specifically designed for the Pro-Flo 4 system, ensuring optimal ignition and fuel timing control.

One of the standout features of the Pro-Flo 4 system is its self-learning capability. The included E-Tuner, controlled via a free Android or iOS app on your smartphone or tablet, guides you through an initial setup wizard. You'll input basic engine information like cubic inches, firing order, and cam profile, and the E-Tuner selects a base calibration. From there, the system continuously learns and optimizes the fuel map as you drive, automatically adjusting for changes in altitude and weather. This means you get a finely tuned engine without needing a laptop or extensive tuning knowledge, while still having advanced options for cold starts and acceleration control. The kit comes complete with all supporting sensors, the ECU, wire harnesses, and a 7-inch Android tablet to get you started.
