T-56 behind 428 CJ

POISNUS · 12-30-2002, 11:19 PM

I was wondering if anyone has a bell-housing to make this work or if anyone has tried it?

I am building a 428 CJ with street usage in mind. I want to put an overdrive in it but stay with a stick (it is a 68 mustang 390 4-speed car). I would like to use a T-56 (like out of a 03 Cobra or Viper).

I have never heard of doing that. With enough money anything can be done. I know of alot cheaper ways to go but they are all with automatics.

What are you going to do with the 390 and t-10?

See http://www.drivetrain.com/fordt56inst.html

Problems I see are the T-56 has integral bell housing and uses the Ford small block bell pattern. This is different AFAIK from the large block bell. Additionally there are input shaft length issues, custom engineering, etc. Seems like this is much harder than using a Tremec TKO II five-speed.

deuce:

Unfortunately I don't have the original equipment. Right now it has a really radical 428CJ (big solid roller, blue thunder intake, fully ported heads, 13.8:1 compression) and is way to crazy for what we want to do with the car. It has a toploader in it now.

Jeff65:

Yeah I pretty much knew the t-56 wouldn't work because of the integral bellhousing, but I was thinking of doing some kind of adapter plate or something to that effect. I would just get a custom driveshaft made.

Thanks for your help Jeff. I might just go with a tremec, since it would bolt into what I have.

POISNUS, you have a PM.

I'd go with a Tremece TKO. The T56 requires significant floorpan clearancing to make fit on an early car. The TKO uses a separate bell housing allowed me to run a scattershield as well.

Check out Dark Horse Performance, Fortes Parts Connection, McLeod, Denny's Driveshaft, and Centerforce for the various parts for what you're doing.
