t5 from 93-97 v6 into a 86 v8 swap??? - Third Generation F-Body Message Boards

I have been trying to gather info on the v6 t-5 93+ model years. Will it bolt up to a 3rdgen v8. So far I have found in the t5 article that the 93 t5 has a longer input shaft. I think it also has a 26 spline shaft though. If the shaft is longer can it be cut off and if so has anyone done this succesfully? Is there an aftermarket spacer for the bellhousing availiable?

I know I read somewhere that the 3rdgen v6 t5 had a longer input shaft also but was a 14 spline. I also found a thread where someone cut this shaft off and used it behind a 3rdgen v8.

I have a 86 Iroc 305. I had a 93 t56 in it but it is broken I found a 94 3.4 v6 t5 for $100 clutch and bellhousing. I have a v8 t5 angle bellhousing. Just need to fix my car temporary. Can it be done?

What I know:

V6 t5 bellhousing is different block to bellhousing bolt pattern.
V6 t5 has longer inputshaft?
v6 t5 has different gearing not perferred for a v8.
v6 t5 is supposedly weaker than a v8 t5
t5 is weak piece of junk
t56 is best solution

Okay I found this tad bit that shoots my swap in the foot.

’93 and newer GM WC T-5 use the Ford case and bolt pattern, so these will not bolt up to standard Chevy bellhousings.
and
the ’93-95 F-body V6 cars got a Ford case with a GM input shaft. There were no V8 T-5 during these years.

Can anyone confirm this?

Would I be better off to find a mustang WC V8 T5 and use some bellhousing adapter?

its true, the 4th gen t5 used the ford bolt pattern case, and only available with the v6. the v8 trans is the t56. the mustang trans has a very different tailshaft housing and shifter, and does not have a torque arm provision
