1940 Ford Tudor Build Thread

This might minimize bad ideas of a blower for a while too.

Don't be talking crazy now! Just look at all the money you saved!

That's what my wife used to say after she'd gone out shopping with her girlfriends - "I had an amazing day! I saved almost $500!!"

Congrats on the win! Looks great on the engine. It would, however, look much better sitting on top of a 6-71 blower. Just sayin', of course!

AND, it only cost $5000.00.....

The set up on the dual manifold works great to play with in your first go a round. When the blower comes, the set up goes right on top. Life could not be sweeter!

I don't believe these will work as draw through. I think you have to step up to the power adder set up and it comes at an extra cost. I didn't want to push my luck and ask for the higher set up. I felt I pushed my luck as far as I should.

Plus another $3500 or more so the Hemi will live. Did I ever mention I have a rusty 72 suburban to build for my wife now? Yeah, there won't be any 671's without a death bed or divorce I'm pretty certain. Haha

The blaster got the hood done and I finally got it picked up. It actually cleaned up pretty well. Now, to use ospho or acid on the rust spots to kill the rust so I can prime it?

I'm surprised! I expect that you're right, but I would have thought that the "power adder setup" would be for turbo applications or ProCharger type setups blowing through the induction system. As it sits now it's "draw through", and on top of a Roots type blower it'd still be "draw through", just at higher rates of flow with the pressure boosted below the rotors. I would have thought that sitting atop the blower would just be like setting atop a bigger engine - just more flow.

The way you roll you'll probably find a guy who wants to pay you for a couple of days labor sorting out his diesel swap with an old 6-71 blower that was rebuilt in 1965 and has been on a shelf since.

I would expect the throttle bodies to be the same, just bigger injectors and programing (which should be able to be updated later).

FWIW, IMHO,it'll look just fine without a hole in the hood for a 6-71. I love blown Hemi's, but I love stock looking 40's better. I have loved 40's since I was little and still regret ever parting with the one I owned.

Well, at least he won't desecrate it with an oil burner

I was getting worried 'bout that boy!

That's what I thought too. I spoke with their tech guy and he said these don't flow enough air and can't provide enough fuel for a supercharger. I asked if it was an idle air bleed issue or? And he said they just don't work on blowers. They say no boost and naturally aspirated in the first paragraph.

Those were my thoughts too. I figured if I leave the engine relatively stock and 2 390 carbs on a 392 is plenty, this 625hp capable system should be plenty for a basically stock under 400CI engine. You can change some parameters in the hand held too.

That's why I'm leaving my original hood alone. If I hate the looks of the hole and scoop, I can always go back to the original hood. I love the lines of a 40 too. Especially a sedan. I've been thinking about frenching the license plate into below the deck lid for a cleaner look but I can't make my mind up on that either.

Ya just never know....... I still have a couple 7.3 Powerstrokes and a good 2wd E4OD. It'd be the only one....... LMAO

OK, I called Fitech today and spoke with a different guy. He laughed and said the other guy wasn't a tech guy. He said no, they're not meant to be ran in boost applications because there is no boost regulating device on these and the programming isn't set up for it. He said the power adder setup they sell does all that. He did say that these would probably work if a person watched the AFR under boost and went in and tuned it according. Dam..... I probably shouldn't have made a second phone call........

Ha Ha, funny how things work out sometimes.

Yeah for sure! I called a local shop that does a lot of EFI tuning. I spoke to him about my situation and what I wanted to do. He explained that the biggest problem is this system has 1 MAP sensor in it and it is only a 1 bar sensor. He says he doesn't know if it can be changed out and this ECU is also not programmed to read anymore than 1 bar. He doesn't hink he can change that. That would have to be a Fitech deal. He said we could give it a shot but he isn't promising anything.

After sleeping on it, I think I will call the Fitech promotional guy and see if I might be able to send these back and pay to upgrade them to the power adder setup. But, I'm hesitant to do this as well. This is because I stopped at a friend of mine's shop yesterday and it sounds like I'm running out of time and about to miss an opportunity of a life time. I'll make a new thread on that.

I think for now I'm going to actually do the right thing. Leave the 671 I got from my buddy on the shelf and just run what I have. Get the car drivable this year because in all reality with everything else I have to do, that could be a stretch as well. But make the 40 run and drive in 2021 is a high priority for me.
