z28 t56 swap...

So it looks like the t56 may be a better option then t-5. I am fairly close to one locally, at a price I can't pass up. I am going to call them in the morning and see if they still have it. The only thing I am not sure of, is what clutch/pressure plate to get...

According to this link, you use a t-5 bell housing, chevy tranny, and "c-6 style" yoke on a shortend driveshaft.

Input spline is 26t, output is 27t. Dose this sound correct to anyone?

nevermind I fvcked that one up... Its saying the t-56 out of a 03-04 only needs that. I would need to change out at least the rear spline on the driveline. What would I need for a bellhousing? Could I just change that out with an aftermarket from d&d? What would need to be done with the clutch?

you would at least need a bellhousing for the T56 and the 302 spacificaly. aftermarket only. might be able to get it through FRPP and or D&D. i would be super suprised if a T5 bellhousing bolts to the T56 but stranger things have happned i suppose.

depending on what t56 you end up with will determine what clutch to get. i forget how many "spline" the cobras have. im pulling mine tomorow so i can verrify/take pics or whatever. you will need an out put shaft yolk to fit the trans and probably some sort of hybrid u joint for the drive shaft. again, not sure on the 5.0 stuff. the bellhousing and dealing with making sure the input and output shafts work with whatever yolks and clutch is the only real big deal with them. prety much like a T5 swap otherwise.

What T56 are you looking at spacifically...?

1995 t56 out of a wrecked z28. It looks like I would need to change the front input shaft out to a 10 spline(stock t-5/aod right?), and get, like you said, some sort of hybrid u-joint/driveshaft... The bell housing is probably gonna be alot of money... D&D shows there's as $449... That would screw me there...

In the link it does say that a t-5 bellhousing bolts up to a chevy block... I think I need to find someone with a t-5 bell housing and a t-56 tranny...

also the ford t-56 uses a 31 spline yoke, where the chevy one uses a 27...

The 31 spline yoke uses the same u-joint as the stock 5.0...

You just use a chevy clutch with a ford pressure plate. The f-body t-56 is the same length as a t-5 apperentally.

FWIW...what does it matter if a T5 bell bolts to a Chev block...?
Aren't you thinking of bolting the T5 bell to a T56 to put behind a Ford engine?

(My g/f's S-10 has a T5 in it...but her truck has the 2.2 engine. 2002. Irrelevant in your case whatsoever...)

Just trying to get the gist of what you're doing lol, not trying to be an ass.

I retract that, there is no way its the same length as a t-5, via the link in my first post. If I have to have the driveshaft shortened anyways, I'll bet it couldn't be too hard to get a 27 sline slip yoke thrown on as well.

not trying to be an ass either ;). What I'm trying to say, is if the t-56 bolts to a t-5 bellhousing, then maybe I could modify a stock 5.0 t-5 bell housing to use with a gm t-56 transmission. It looks like the only thing I really have to worry about on that part is how long the input shaft spline is.

well, its just not going to be that simple. first thing your going to have to verrify is if a T5 bellhousing that fits the ford 302 will also fit the T56. I hadnt looked at the link until just now and i can tell you at the very least his info on the 03-04 cobra T56 is in-correct.

Heres what i had to do (keep in mine im bolting it to a 4.6 modular.

03-04 cobra trans with factory bell housing. didnt even touch the clutch/PP and i forget how many splines were on it.

T45 yolk wouldnt work. 3650 (i think) yolk with a hybrid joint solved this. had the aluminum drive shaft shortened. done deal.

I will be hitting this hard tommorrow some time. Its to late to make alot of sense out of it all.

GM T-56 six speed universal fit

Description: This T-56 bolts to both a T-5 or a Muncie/Borg Warner bellhousing. It comes with a 2.97 1st, 2.07 2nd, 1.43 3rd 1:1 4th, .80 5th & .62 6th.

Installation Notes: NOTE*** Transmission tunnel modifications are most likely needed. This T-56 does not include a bellhousing. It has a 26-spline input and a 27-spline output.

I want to get more info from this guy.

well, if it bolts right up to a ford T5 bellhousing that would be A cool and B news to me. like you said, another thing to consider would be the length of the input shavt vs. the depth of the BH.
