I installed the Pro Flo 4 on my 1970 GTO Judge. Sequential port EFI is the game changer here. Throw all the throttle body systems and carburetors away and install this kit. Plus the software and tablet interface is far superior to the other companies at this price point. I have a 4 speed and the throttle response and mixture quality is perfect. Install new spark plugs and be amazed at how perfectly even they look after running with this system. My car can idle and cruise now at a much leaner mixture. Watch for the article in a future issue of Hot Rod magazine with my car.
Ive installed many kits at work, the FiTech are junk every one we've installed came back with injectors failing. The Sniper we've never had a single one come back and they run pretty good. For my truck how ever I am looking at this as if I did fuel injection swap I want sequential fuel injection. Problem I keep running into is I have a C6 and ive yet to find a kit that offers a Ford Kickdown hook up to retain the kick down rod. Many talk about doing a cable conversion but that is just tacky in my eyes since youll need so much cable slack to ensure the kick down only engages fully at wide open throttle. The other problem I keep running into is no one at holley or edelbrock can tell me if a OE factory cruise control can pull the throttle open. I don't think vacuum operated cruise control will work on the sniper as those are quite stiff. Not sure on the edelbrock, and I already have a performer intake, 1" phenolic spacer, and a 600cfm summit carb. Hate to spend $1300 on more parts if they wont work in the first place.
Nice video, and it was good to see you get it sorted out. I just got one of these for my ride, and read all the instructions carefully first (twice) and laid it all out on the floor to make sure everything was here and the connectors were working. I haven't installed it yet, but I see that a lot of the problems you had with initial install were addressed in the instructions (fuel pump, valve covers off when seating manifold, etc.) - I don't know if they have been added since your install, but advice for guys buying one of these, all EFI systems have lots of sensors and the setup is super important, so read up and play with it before you get down to the down and dirty install. I had to study up on some terms I didn't know and I'm doing youtube research now (hello!), and now I'm feeling pretty confident about the install. I used to install stuff before reading the instructions - sometimes was lucky and sometimes not. But this electronic stuff is not nuts and bolts, and if you have problems, tech support is going to ask you if you did this and that, and will send you to fix it and have you call them back after. As an old fart who has spent many hours scratching my head at problems I have created, I can say it's worth the extra time! Thanks for making this video, and to the folks that think it's a waste of money, just price a great 1000 cfm carb, a performance manifold, a digital ignition controller and a distributor and compare that to the Edelbrock kit, because you get all that, the whole system, in the box. I've found that off the shelf carbs are never perfect, and you have to have a dyno and a drawerful of jets to tune a carb to run as well as EFI. To each his own, but this kit ain't a waste of money!!! And it's made in USA!!!
I did the holley efi and it was alot cheaper than the eldelbrock system. I used the procomp 351w efi intake and fuel rails , aeromotive regulator , I bought the universal holley wiring kit , and holley efi throttle body . All said and done I had a little over 1800 in the system . I was able to reuse my msd distributor , I had to synchronize the distributor which was a pita . The best feature is all the upgrades and support with holley vs eldelbrock in my opinion.
9:15 you only need the vacuum line for boost reference. Naturally Aspirated engines do not require the line nor the connection on the regulator. A PSI gauge mounted to the output helps make setting and checking easy and convenient.
Glad you finally got it installed, loving mine. I yanked out all the fitech stuff and went with Edelbrock's sump pump, seems to work pretty good with the added benefit of the plug and play of it with the ecm.
@@williamwright6157 just a single tank, the mechanical fuel pump supplies fuel to a sump and an electrical fuel pump inside brings the pressure up to 52 psi and then fills the fuel rails. This also prevents sending air to the injectors which can happen when fuel is sloshing around in the tank.
Very nice John, glad to see your enjoying the pro flo 4, took a long time for the video but I have to say it made my day can't wait to do mine, cheers brother.
Tiko 433 I am running the Walbro GSL392 in line fuel pump. It was one of the few recommended by Edelbrock. The amp draw is low enough so I didn’t need to use a relay.
You probably already know this and its after the fact but from what I've seen is you needed an open spacer under the FiTech or a notch in the divider on your intake to run the FiTech or units like it.
And of course multisport efi will be better than tbi intake injection. Kind of a no brainer the edelbrock will have better drivability and throttle response etc.
disculpa amigo, espero que me puedas responder mis preguntas las cuales son ¿como controla la inyección de combustible el sistema de edelbrock?, y ¿como es que dirige la inyección al cilindro que debe ir ya que no cuenta de sensores ckp y cmp?
I was looking into installing this on my 66 bronco w/ a 302 but I have a couple of questions regarding the fuel pump and the distributor. I'm trying to decide if I should go with the edelbrock fuel sump/surge kit they offer or just get an in-line fuel pump and if so what in-line fuel pump would you recommend? Now I'm wondering if I would need their distributor because I currently have a gm hei distributor on mine. Any advice would be very helpful
Good Job brother, things don't always go as expected especially when using aftermarket systems. Way to stick with it, always remember the "ignition Tri-Angle"... Fuel, Air, ignition. A suggestion for anyone working on engines, a smoke machine. One of the first things I did on the stand after the ProFlow 4 install was smoke tested my intake for intake sealing issues. I just built a 400 SBF stroker going in an 83 Bronco. I decided to go with the Edlebrock Proflow 4. Engine went in to the bay yesterday and today will be getting the fuel system ready with new 10amp fuel pump, regulator and all 6AN routing. You are 3 years in to your install now, are you happy with the injection system? -- Mike
Sounds like a lot of your issues came from trying to marry FiTech parts to the Edelbrock system. Those of us going with a virgin install would most likely avoid many of those issues. Totally digging the fuel rail system vs. the TBI. FiTech was always putting off getting their fuel rail setup on the market. I am currently running an Edelbrock Performer Air Gap and Edelbrock 650 carburetor. The entire system will get pulled and replaced with a new fuel tank with an in tank fuel pump and new lines. I definitely see an Edelbrock ProFlo XT in my future. Thanks for the videos, really helped making my decision.
I have a Holley in tank pump that I’m going to use with the Pro Flo 4. Pump directions say run a ground directly to the battery and the power line goes to the relay. But you had mentioned that the pro flo uses the negative side to switch on/off. This sounds like I could have the problem you did with the fitech unit not shutting off. Can you elaborate more on how you wired into the pro flo with the relay?
John great video! I have watched all of your videos pretty much thus far. I am doing a complete frame off restore on my 69. Question about the fuel pump system etc.. Did you change this from what it was with the Fitech? Did you use the Fitech fuel pump kit and keep the same or did you replace certain parts? Edel Brock calls for 57gph min for fuel pump.. Thanks!
Hi Jon---yanked the FITECH off my '66 and am in the middle of installing the Edelbrock PF4. I think I recall one of your videos about trying to use the Fitech fuel pump but it not working with your new set up. Which video was that? Thanks!
Yeah! I've been waiting for this video! Great job! Glad You got it running, surprised that you didn't see anything wrong with the intake gaskets to indicate a vacuum leak. is the dyno test next?
Hey Jon---did you end up using/needing the Edelbrock 8401 Kick Down plate? Getting ready to covert my 66 from FiTech to the PF4 and can't seem to find that plate in stock anywhere...
Hey! I have just installed pf4 on my 289 Mustang. Mine says it runs lean 22.8 witch makes the computer (I think) pump in extra fuel. Every time I start it now it has waay too much unburnt fuel coming out of the exhaust. Did the O2 sensor test from edelbrock RU-vid guide on O2 sensors and it works fine. I think I might have the same intake problem as you? I know it is hard for you to tell but I might suspect I did something wrong somewhere along the line
@@NashvilleEarlyBronco I got it sorted. Even though O2 sensor "worked" it didn't work correct. Got a new one and raised the fuel pressure and now everything is perfect
Hey John, How do you think the height of this pro flo is compared to your original intake with the fitech? Is your air breather closer or further from hitting the hood? or about the same?
Great video! Bought the Edelbrock pro flo and will be installing soon. Question, you list the Edelbrock 3594 fuel pump which is advertised as a 10A pump, so I wouldn't need the relay you talk about, right? Thanks!!!!
So, since it’s been - what - 4 years 😳 Do you still like the Pro-Flo? What kind of gas mileage do you get? Any suggestions for someone (me) considering installing this in a ‘94 F250 351W ZF5 4x4? I’m hoping to get away from the ‘Bank’ style injector firing vs the Sequential Port FI that the Edelbrock system provides. Kewl video - Thanks!
Hey Larry! The vacuum from the engine tells the regulator when to add in more fuel because of acceleration. Kind of like the cars that had vacuum running to the distributor for the same reason
I went with the Edelbrock Pro Flow 4 on my 1969 Bronco with a stock motor. I'm experiencing hood clearance issues so I'm wondering what air cleaner you or any of your subscribers used. Thanks for the great videos. Chuck
@@NashvilleEarlyBronco i wish i would of known about this unit before i did my rebuild on my k5 blazer..if you’re doing a complete rebuild with everything new this is the way to go..Since it comes with the manifold, distributor and efi system thats a bargain.
I personally like the holley system better. I have the terminator tbi which uses a Holley HP ecu. Better firmware and laptop software. More tuneable, modular and upgradable. Aslo what i dont like about the pro flow is that it uses a single plane intake wich gives up a ton of low speed torque for a little high speed H.P. out at 7000 rpm. Not great for a street car or a truck.
Biggest problem with fitech is the ecu is mounted to the throttle body. As you know computers and heat do not like each other. It's a cool for crusing car shows and what not but cross the country reliability just is not their.
OK, I am getting the edelbrock proflow 4 I have done a lot of research before I make the purchase, all the issues you mention, I already knew. I guess what I am saying before jumping into this do research on what parts are needed, and check if the parts are correct, and follow instructions to the T...this video is nearly useless, your basically saying I know nothing about this setup or what's expected.. it's like taking one step forward and 5 steps backwards.
Could do without the rock concert going on in the background. Don't need it, you and the install is what I want to concentrate on. Thanks, good video, sorry the music sucks though.
Those are nice but I would have to invest in a 6 speed transmission first. Without a good overdrive transmission the mpg benefits of EFI won’t really shine. I’ve never had a problem daily driving a carb engine or starting them. It’s the old 3 speed auto transmissions that drive me nuts! Lol I’ve drove my old Chevy C10 in Nashville traffic many times. The carb was never the problem, it’s the screaming RPMs trying to run with modern traffic lol. Nashville is a nascar track lol 😂
Nashville Early Bronco I put the Fitch on my 302 f100, I ran the retro in tank pump for fuel, 58psi. 3k miles no issues and thank you for the videos. Now I want to run this pro flow 4 on my Pontiac 455 ci. 7.5L.
i know 3 or 4 guys running fitech and have almost no issues i was thinking of getting a 2bbl for my 318 poly . i have herd of lots of issues with edelbrock heads so go figure
