Edelbrock Pro Flo 4

Good morning everyone-

I am planning to add EFI to my car over the winter and am wondering if anyone has experience with the Pro Flo 4. The Holley Sniper is a popular option and I’ve been thinking a lot about it, but can’t help but wonder if it’s somewhat antiquated at this point. Edelbrock stopped making their TBI system to focus on the Pro Flo. It’s likely only a matter of time before Holley does the same. If going EFI it makes sense to me to go multi-port to get the most out of the technology. I know Edelbrock is more expensive, but I’m of the buy once, cry once mindset. I appreciate your thoughts. Have a great Monday!

I'm considering going EFI myself. Have no knowledge of the new Edelbrock system, but never heard anything but good things about the antiquated Holley Sniper, lol. Subscribed to this thread for other opinions.

I likewise would not call the Holley Sniper "antiquated," although I do like Edelbrock products. But no way I'm paying $600 more just to get theirs.

I'm planning on running the pro Flo 4 on my 393 build. After doing some research and watching a few YT shows about it, I believe it's worth the cost difference.

Very happy with my "antiquated" Sniper system. Having run Edelbrock and Holley 670 SA carbs on the same motor, I can say that the car has never run better and/or stronger.

That Pro Flo system does look cool.
It does have some cool options like the Bluetooth tablet compatibility. I wish the Sniper had that vs corded.

Since Iím running a cleveland, itís not an option for me...

Iíve already purchased the Super Sniper and I do like hearing all the wonderful reviews.
It would appear that from a shear simplicity and complexity, the Sniper wins hands down.
It would appear the Pro Flow has significantly more parts and requires an intake change etc.
The bolt on and go is sure nice.

Just my $.02 Worth which wonít get you a piece of bubble gum.

Looks like a decent setup for a good price. Not much more than the cost of the Sniper plus an intake.

I wouldn't call the TBI systems "antiquated", more like an option for those that don't want to replace their current intake. Hopefully they will eventually cover the full spectrum of Ford engines.



Never understood why they named their EFI systems after an air filter that everyone has a horror story about....

Nothing worthwhile is ever quick, cheap or easy, those that can't do, complain

Looks like a nice complete system. I've always thought direct port injection is a better system. The $1600-1800 range is a decent cost for the package. !'d go this route if, I was looking.......

I looked into this a while ago. I talked to a few other guys on forums who are into EFI systems way more than I will ever be. there are some good features with this like sequential firing vs batch firing. Down side is, its pretty vauge on how much HP it can handle. one guy tore it apart and said that the injectors were pretty small and cheap, making higher HP motors probably unable to use this. With that said, none of them had any experience with upgrades on them and probably for most of us who arnt running our cars like wild apes, it'll work fine. One thing that is good about the Fitech is that Bosch injectors fit and the system can handle quite a jump in injector size. I would like to give it a try, but my fitech seems to be working just fine.

Ha! Perhaps antiquated was too strong of a word, but certainly I think multi-port injection is more advanced technology. Itís much closer to what modern vehicles are running today. I just donít want to buy another Betamax. For you young folks, google that. All kidding aside, if I am going through the hassle of upgrading and running additional fuel lines etc, it makes sense to me to get the most advanced system I can. Changing the manifold is no big deal. From what I have read so far, the Pro Flo seems to get good reviews. Thanks for everyoneís thoughts.

Not to mention the pro Flo is designed to run as a system. There's no dispute on what intake to run etc...

I like the look of the system. One thing I learned from getting one of the first FiTech systems is don't be an early buyer, let the other guys work out the bugs and buy a year or 2 later when the bugs are worked out and the competition comes out with a similar system driving prices down.

I think the hight of the manifold and throttle body could be an issue at least on 65-66 cars. The EFI system adds up to about 8 9/16". My Performer 289 manifold, FiTech TBI, and one inch spacer add up to 7 9/16" and with a repo HiPo air cleaner on top I've got less than a 1/2" clearance from the top of the air cleaner to the hood. Not that I should be considering such upgrades anyway!

I would think it should be shorter as the only thing on top of the intake is the throttle blades.
