Edelbrock Pro Flo 4 EFI System Seq Port Pontiac 326-455ci 625 Max HP 35lb/hr Satin Finish

If you're looking to upgrade your classic Pontiac V8 with modern electronic fuel injection, the Edelbrock Pro-Flo 4 EFI System is a solid option. This kit is designed for Pontiac 326 through 455 cubic inch engines, covering a wide range of popular models like the Bonneville, Catalina, Firebird, and GTO from the late 50s through the late 70s. It replaces your carburetor and intake manifold with a complete EFI setup that offers improved drivability, easier starting, and better fuel economy compared to older systems.

This Pro-Flo 4 system includes a traditional 4150-style single plane intake manifold with a satin finish, paired with 35 lb/hr fuel injectors that are capable of supporting up to 550 horsepower at 58 psi of fuel pressure. The system features an updated ECU with a faster processor and a waterproof design, making it more reliable. Its improved Bluetooth connectivity ensures a stable connection to the E-Tuner 4 app, which you'll use on your Android or iOS device to tune the system. The app offers a simple setup wizard and allows for advanced tuning of air-fuel ratios, ignition timing, idle speed, and more, all while the ECU's self-learning capability continually refines the calibration for optimal performance. This system does not require a laptop for tuning, simplifying the process significantly.

Included with the EFI system is a plug-and-play distributor and a high-quality, fully terminated harness made in the USA with clearly labeled connections to make installation as straightforward as possible. The system comes preloaded with 80 dyno-tuned calibrations, and the free E-Tuner 4 app provides multiple dash displays to monitor your engine's vital signs. While this system offers advanced tuning capabilities, it retains the user-friendly simplicity that the Pro-Flo line is known for.
