The Pro-Flo 4 is easy to install, and tuning it could not be any more simple. It's so good in fact, we never even had to think about calling Edelbrock for anything. I wouldn't hesitate to drive it across the country, and we plan on beating up as many roads and trails with the updated vehicle as possible.

The secret to the PRO-FLO 4 system is its upgraded ECU: it's got a faster processor, measures half the depth of earlier versions and is all wrapped up in a waterproof design that offers maximum control over: fuel-air ratios. ignition curve. acceleration fuel.

Edelbrock Pro-Flo 4 Dual-Quad HEMI EFI System #35670 is intended for use with 1964-71 Chrysler Gen II 426-572 HEMI engines operating in the 2,500-6,500+ RPM range.
