Has anyone put a pro flo 4 on there 318 engine? If so how did it go?

 

Mostly Carbureted here.... Sorry..
Whats the issue you have run into or are having?

 

Whatever its worth, I've asked guys with these systems at shows and cruises how they ran and worked out. All of them weren't happy and were switching back to carbs. Keep in mind these were all modified builds that may have contributed to it. .

 

If I remember correctly Edelbrock was originally the FAST line of fuel injection but is now owned by Holley, so it’s hard to tell what you’re getting now. but it probably depends upon how much cam you have and how tunable the efi is no matter who makes it.

 

Holley drove me absolutely nuts back when it came out with that "Terminator" deal.... It was so hard to deal with, we went back to a 1050 Dominator and only used the ignition and launch control and rev limiter of the Holley set up... And I never even dared trying to use the N0S on the system, I just put it on a throttle switch, could never get the timing ramp to work rite..

 

Yeah I’m not enthusiastic about any of the entry EFI offerings, you need the spend some big bucks to get everything you need.

 

It's worth mentioning that the Pro-Flo 4 is only listed for use on a 318 if it's using 340 or 360 cylinder heads. Also, The intake manifold that comes with the kit most likely won't bolt to magnum cylinder heads since the fastener angles are different compared to the LAs.

The only efi system I have experience is the FiTech TBI unit... it works but, it's not as good as a carburetor, I'll probably switch back to carb if my unit ever burns out.. 5 years so far.

 

Good Points....

The FiTech i understand has a easy Start up ???? But I do understand that it is a little picky with its ground circuits... And if the grounds are weak you can run in circles pulling your hair out..

 

All of the basic EFI kits don’t make the power that a carb makes, I’ve seen it many times on the dyno where the carb makes more power everywhere in the curve than the EFI kits.
