i am wanting to swap in the drivetrain from a 97-01 Explorer with the GT40 5.0 V8 ... over into my 70 Grabber. Has anyone attempted this? was wondering how i could hook up my speedo. since the explorer has no cable.. would i be better off swapping in the drivetrain from a late 80s early 90s mustang/crown vic ??
Are the heads GT40 heads or GT40P heads? if its a GT40 then it will swap in no problem. P's will give you header problems i think the 4R70W transmission requires a computer to run it. TCI makes a stand alone unit for the AODE, but i dont know if anyone makes one for the 4R70W. http://www.tciauto.com/Products/Electronics/ The easiest way would be if you carb that engine, and install a C4 or AOD behind it.
x2. if you do a search on p heads the drivers side plugs will about rub the header. The non p heads have 3 bars on front and the p heads have 4 bars on front
If he swaps in the engine and trans he will have the computer to run it from the donor. Putting a carb on it defeats the idea behind the swap. I wonder if there will be enough room in the tunnel for that transmission...
i think that there is an adaptor that takes the digital signal from the speed sensor on the trans and then transforms it to a mechanical signal that turns a speedo cable. the trans tunnel may be to small for that trans, not sure but something to look into. the last little detail is the shock tower braces wont clear the upper intake and require custom ones to be made.
The Explorer gets the speedo reading off the rearend. Holley makes an electronic unit that bolts onto their carbs that will run an electronic transmission. Summit lists it in their catalog.
If you dont want to deal with the computers, you may be best just to yank the heads from the Explorer (if theyre the non-P) and put 'em on a Mustang mill. If you really want a nice trans, yank the wide ratio gearset from the Explorer (99+ is better) and put it into the AOD.
He never said what his goals were...so what would the purpose of the swap be? Fuel economy? Power? Simplicity? So you can't say that carbing that engine would defeat the purpose of the swap...because we don't know what he wants. Plus i just said that going with carburation is the easiest route, not the best. IF you want to keep the engine and tranny AS IS, you will have to deal with the wiring, drive shaft issues, Modifications to fit the transmission.(i haven't seen anyone swap in a 4R70W into a maverick yet).... If he does keep the electronics's you are correct, that would run the transmission. But that's only if he was to run fuel injection.
What's the point in doing that ? Same short block for both engines. All you have to do is replace the intake assembly, the camshaft position stub, replace it with a steel geared distributor and enjoy. And add a set of 1.7 pedestal roller rockers to boost the lift specs of the Explorer cam.
Basically the same, yes, just forged pistons for the Mustang, plus a slightly better cam with a bit more duration.
wow hit a nerve with that one huh...i have always been a true Mav fan also like the GT40 setup in the explorers and for some time now i have been pondering a swap.i have not bought the donor explorer yet and it would be a 2wd if i did,,i just wanted to see if anyone else had attempted it before i sink a bunch of time and money then end up with a lot of scrap parts..i grew up riding around and driving Carburated vehicles that alone should tell you why i want EFI
Well I was just using the not so common common sense, why would you pick this combo for a donor if you were looking to go carbed? If a carbed motor was the desire you would be money and horse power ahead buying a crate motor. I was just reading between the lines and it looks like I wasn't too far off......... I agree, I've had my share of monkeying with carbs so I'm going with injection too. I have already bought a GT40/Explorer intake setup and it looks good on the engine. You will have to mod the braces but that's trivial. Another cool feature is the EGR elbow. You can point the throttle body forward with it and it will clear the brace leaving you with only one side to alter. I mounted mine with the throttle body on the drivers side and I might even be able to use the stock throttle cable (depending on how the linkage on the TB is setup, it's still in transit). I say go for it!
The forged pistons is a non issue though unless you're going to NOS it. There's not enough difference in the cam profile to want to swap it from one to another. Either works great with a carb.
