Video: Edelbrock Reveals All-New Gen II 426 Hemi Pro-Flo 4 EFI System


Edelbrock’s growing lineup of electronic fuel injection systems is soon to include a base calibration package for Mother Mopar’s monster: the Gen II Hemi. According to the Edelbrock Performance Facebook page, the Pro-Flo 4 system will soon have a dyno-tested calibration available for the Gen II Hemi with dual-quad induction. Their 528 cubic inch test mule belted out 694 horsepower and 611 ft-lbs of torque at the flywheel, all with the driveability and reliability of modern fuel injection. Details are slim, but it looks to be a Mopar 528 crate engine with aluminum Edelbrock Victor Jr. heads, an EFI-ready twin-four manifold (Edelbrock #75245), and MSD ignition.

Tuning a single carb is one thing, but getting two four-barrels to work in unison on a Hemi has always been something of an art. The Pro-Flo 4 takes care of that with carefully crafted base calibrations that self-learn as you tool around in your thumper. Also keep in mind that the Pro-Flo 4 is different than most in that it delivers fuel via sequential injection.

Many aftermarket EFI systems have the injectors located in the throttle body, similar to the way a carburetor functions. Pro-Flo 4 locates the fuel injectors right at the end of the intake runners so that fuel is precisely distributed into the combustion chamber for high-quality atomization and ultimate performance. The throttle bodies are basically giant air valves ready to swing open wide when your Hemi says, “Feed me!”
