Edelbrock Pro Flo 4 EFI

I have it in my garage waiting to go on a 68 charger. That car was previously running a previous pro-flo multi-point EFI system. The difference was it wasn't a self tuning setup. After several costly trips to the dyno to try and get a base set up I saw the light...

The Pro-Flo 4 has a LOT of improvements over the pro-flo 3 from what I can tell. It is a very a nice kit. I wish I could tell you how it runs but I haven't had time to install it yet.

There was a big height difference on the manifolds though, so the new kit required a hood scoop to fit the charger. Also something to note, I blew up 3 or 4 of the external fuel pumps that are an option when you buy the kit. Do yourself a favor and spend the money on an in-tank fuel pump setup and you will be saving money in the long run.

Nice! Thanks for your follow up. I was thinking that this system was too spendy for the FABO crew or something because few have chimed in.

So which version was the car running previously? Was it a Pro Flo 3, or something older? Is it running a smallblock or big block?

I did wonder about intake height because I didn't want to cut a hole in the hood if I ever decided to go with this type of EFI.

I talked to the guy who wrote the manual for the Pro Flo 4 and he was very enthusiastic about it. This was at the recent even at the Irwindale Speedway in California.

He told me that they do extensive testing in the winter time. They drive several cars equipped with the Pro Flo from central california down the coast and all the way up to Big Bear (that's about 6,500 feet elevation), again in the Winter time. They leave the cars parked overnight and fire it up in the morning to test cold weather starts (Big Bear is below freezing in the winter). Obviously, going from the coast to Big Bear tests out the self-learning when it comes to elevation changes.

That really got me excited because after having all sorts of problems going up to Big Bear with an Edelbrock AVS carb, I thought it would be cool to have an EFI setup that I didn't have to touch no matter what elevation I'm at.

I'm eager to hear how it runs for you. I'm not looking to make horsepower (well that would be a bonus), but instead looking for MPG and easy driving anywhere I go. My Duster is no trailer queen. It gets driven!
