I'm new on here but I need help I got a 1991 f350 singal cab dually 2wd stripped chassie 10ft bed with the 7.5l aan a c4 aod automatic I believe in it and I bought it as a boom truck with no transmission in it and now I removed boom and utility body and all lines and gas tanks and it has the Dana 70 in the rear and I have a 94 Bronco that was wroled in an accident and all is good on it has a 351w and a aod trans I took them out and I want to put the ttb setup under my f350 but it's 5 lug so will it fit and could I change the axles in it to 8 lug and I have a 7.3 turbo and an s92 c6 transmission for it and I'm gonna put a flat bed on it and I'm not shure if the rear would work so same problem but bigger truck and the bronco is a d50 I believe

 

C4 is a 3 speed light duty trans although it can be built up for handle some high horsepower (a friend had one in his 10 second Mustang. The AOD is a 4speed trans but I don't believe they ever put that trans behind a 460. Imo, you should be looking for a Dana 60 for the front.

I think you could use the outers from an F-250 to get the 8 lug pattern. The Bronco TTB is the same as what was on an F-150 and is a Dana 44 not a Dana 50.

 

The AOD never came behind anything other than a 302 in trucks. The Bronco either has a 302 or E4OD or someone swapped one or the other at some point. Anything other than a 302 in front of a stock AOD isn't advised. They can be built to hold back a lot of horsepower but that requires a lot of $$. The 300, 302 and 351 share a bell housing pattern. The 460 has a different pattern so it won't swap. Same for the 7.3, it gets its own bell-housing pattern. The C4 never went in trucks. If it's an F350 is probably has a Sterling 10.25, not a D70. The D50 never went in Broncos. It's a D44. There's an 8-lug swap (Google it) if you really want to do that but a D60 swap would probably be better. Swapping for 05+ Super duty axles would be another possibility as well since your truck is already set up for coil springs. Your 460 truck has an E4OD transmission.


You really need to do some research about what you have and what can swap with what. Most of the stuff you've said is either not quite right or is somewhat wrong and most of it is really basic stuff that's only a Google search away (e.g "what axle does a 1994 Bronco have?"). IMO if you have an internet connection and can post here you should already know that your 460 doesn't have a c4 behind it. If you go through with swapping stuff around it will be a lot easier/cheaper/better if you know what you're doing before you start.

 

I know I meant I have a c6 with an np205 and a 7.3l wich it has the same bolt pattern as the 460 and 351m and 400m and I know it had a 44 in front of the bronco auto correct did it lol

 

The 460, 351M and 400 all share a bellhousing. The 7.3 is different. You can adapt a standard bell from a 460 to a 7.3, but not an auto. There isn't enough material to modify it.

 

NP 205: Was this a 78/79 FSB?

 

I got the trans mission form a guy that said I try came out of a 1980 f250 with a 400m big block

 

... sort of. The bellhousing bolt pattern is the same, but the axial offset from the bellhousing mounting surface to the flywheel is different (or something like that). You end up needing weird adapters to put a 460 trans on a 351M or 400. Some guys on the '80 - '86 forum have worked through all of the details. But it's not as simple as putting a 351W trans on a 300 or 302. And I don't know what the issues would be putting a 351M / 400 trans on a big block.

 

I just decided to put a 460 back in the truck and not the 7.3 turbo

 

For an automatic, there are no issues. I have a C6 from a 1979 Bronco (351M) behind the EFI 460 in my 1989 F250. It has been there for a year now.

 

I got the ttb from the bronco in the f350 and its an dually sterling 10.25 in the back and I want to convert the ttb signal wheel base into an dually could I use the dually spindles off the 2wd and put them on the ttb or what do I have to do and the ttb bolted right in I'm running the 5 lug in it now to move it around yard

 

If it is a D50 TTB all you need is D60 DRW Hubs ...

I've done the conversion, traded with a gent on here years ago, My D50 SRW's for his D60 DRW's.

I was told that it was an Dana 44 in the front but it looks the same as the Dana 50 i have in my
96 f250 4x4 auto with the D50 in the front besides the 96 is an leaf spring not coil

 

As I understand the easiest id for the front is:
If the Wheel Hub is the same size as the Locker it's a d44.
If the Wheel Hub is larger than the Locker it's a d50.

It's definitely a dana 44 and I looked up new the spindle goes for $425 plus
