Product Details

Edelbrock Pro-Flo 4 EFI systems provide you with a high performance traditional-style intake and 4150-style throttle body. Unlike regular throttle body EFI systems, Pro-Flo 4 features the fuel rails and individual injectors for each cylinder mounted on the manifold. This Edelbrock design produces the best fuel atomization and distribution for the ultimate performance, as well as delivering the most control and the most efficient way to deliver fuel to your engine. Along with innovative design, Pro-Flo 4 systems have the latest technology with an all-new ECU, and even more features for advanced tuning, with the key being their exclusive E-Tuner app with base calibrations developed on their dyno.

    Everything in the kit feels quality and was well packaged. I am still working out some kinks on my install on my 84, but overall I am very pleased. I have to mention that I am having other issues, a miss on cylinder 6 and/or 8, but even then the truck starts every time and holds a smooth idle. Sometimes the idle climbs, but I believe that is an issue with my engine not the kit. I used the edelbrock fuel surge tank and it was plug and play with the proflo4 harness. Only 2 things I can remember having to change to make everything work. I moved the fuel crossover to the front of the fuel rails to clear my AC compressor (a 90* hose fitting probably would have resolved the issue). The second was that I had to add a diode to the alternator wiring to get the truck to turn off when I turned off the ignition. I found a plug and play harness extension with the diode built in. Until I got that diode, I just wired a kill switch into the signal wire for the proflo4 ecm. All in all, the kit is great. Throttle response is great. The whole getup is quality.
