77 Ford Cummins

hi guys and gals,im new to this site and looking for anyone who has done a cummins transplant into there old ford.
i have the donor pickup,a 97 dodge 12V. i have a few question about this truck being that its a 2wd and my ford is 4wd. can i marry my transfer case to the transmission in the dodge? this is my first question.
also wondering if anyone has done business with fordcummins? i particular im wondering about there motor mounts.

The search engine will be your friend, as many people have done this many different ways.

To answer the 2wd to 4wd question, you could use a divorced tcase and keep the 2wd trans behind the cummins.

You cant marry the transfer to your trans because of it being 2wd but as stated you can use a divorced np 205 out of a 73-77.5 F-250 4wd.

As far as engine mounts what is your truck?

That option is reall up to you. If you get a 4wd trans you are still lookin at $350-$400 for an adapter to put the ford transfercase behind the dodge transmission. I did my first conversion on a 79 f-250 which has the smae frame as yours. Alot of the swap depends on you ability to fabricate and your budget.

Depends if you want to keep the trans from the donor truck. Would probably be a lot cheaper and easier to keep the 2wd trans from the dodge truck and put a divorced tcase in.

A bit of a side not, but please dont tell me that you plan on keeping the cummins stock when you swap it in.

well sounds like the divorced t-case is the ticket then. the guy who owns the donor has done some tweaking already. so for now ill just get it in there and next winter it s gonna get overhauled then it will be ready for some super tuning
have you done the swap yourself by chance? fordcummins sells motor mounts so i need to call them soon. do you know if these many cab mods to do other than the clutch master cyl? seems like a fairly straight forward swap but all the input i can get the better. thanks much for responding to my post!!! happy new year!!!

I did the swap in my 77.5. Used a 93 from a 2wd, the dodge auto transmission and a divorced transfer case. Haven't regretted it for a minute.

None of which were ever finished


That being said - I'm not one to talk as my 4 year project isn't done yet either.

I do have the 2wd trans in my '74 highboy with a divorced t-case though and like it so far... Which doesn't count for much since it's still sitting in the shop
