I beleave it has the same bellhouse bolt pattarn as the SB V8. I would switch to a better trany like a C4, AOD, or T5. I dont know anything about C5s but they do make alot of upgrades for the tranys I listed. I have a AOD that needs rebuilt, you can have it if you pick it up.


A c5 IS a c4, but with a lockup converter (which is good for a driver) and metric fasteners.

86TBuzzard - Did you end up with 3.73's from the factory, or do you stock car race?

Bruce M - My previous research indicates that you are correct, it is a Smallblock V8 bolt pattern. Also, I appreciate your offer of the AOD, but I don't believe I'll be making it out to the east coast anytime soon.

you do need a few things that would help like
 3:73 gears with limited slip
mac longtube headers(look under 99-03 mustang)  and exhaust
then that would make a difference. if you go to a salvage yard look for a aerostar van with a 7.5 rear end. they have 3:73 and 4:10 gears from the factory they will fit your tbird.

Wish I had known the Aerostar's rearend was 7.5, I would have grabbed the gears when I pulled the driveshaft last time I was at the yard. I have a 7.5 Trac-Loc rearend out of a stang already. Bummer that I can't just swap the whole rear end into the bird, but I believe there are various length differences involved.

Already have 2 1/4" Dual Pipe exhaust w/ Hiflow Cat, can't get dual cats due to emissions regulations.

I'm not sure the longtubes would give me all that much unless I  A) Put a blower on it, or B)Did a port job on it. The Factory shorty headers are pretty spiff already.

But really, I believe the 5-Speed would be the best overall upgrade.

I am pretty sure the mustang stuff is the same length as your car as far as the axle goes.

I honestly dont think you could exceed the cost of a new car buy installing new *stock* parts everywhere in your coug our tbird. Its just plain impossible. You could revamp the entire drivetrain/engine/suspenstion and still come out ahead.

First, CLARIFY yourself.  "Axle" can mean a lot of things to a lot of people.  To some it's an entire loaded rear end, to others it's just a housing, while to others it's just an axle.

There is SO much "pretty sure" and "I think" info floating around about this subject that we even have 3 sticky threads on it in the Driveline section of this forum, with multiple others from folks who asked before looking.

If you aren't positive, don't guess.  Better yet, use the resources we already have here on the site to check yourself.

Your response is only 1/3 correct.  ONLY the rear axle HOUSING on his '83 is the same width as the Fox Mustang stuff.

Sorry, but patience is thin these days.

I apologize chuck. I was going to dig deeper into it and edit my post, but I forgot to come back to it.

I had forgotten this existed. What were your driving impressions once you got the carb sorted out?

From other threads, looks like you're also putting a T-5 in it?

Wowzers! Dead threads alive!  I enjoyed the  out of it when it was running right(Distributor issues). She pulls like crazy through most of the gears with 3.73's. She was a bit of a dog in 5th, but that was from the runners being so short, there was just a giant open plenum, so basically no torque. Ok, minimal torque.

  That is one of the reasons I'm installing EFI back on the motor, is because I don't feel like building a real intake manifold for it to get some of that back. I'm using a truck manifold for this go-round, and it is a torque monster.(Should be, anyway)
