5 speed trans question

I have a 5 speed from an '85 2.8l sitting in my garage. A t5 right? The only standard that was factory behind the 2.8's and the 305's was the T5? I have a fellow that would like it but he seems to think there was a different 5 speed behind the v8's. We just need the info to make a deal.

Thanks

From: out of my mind; be back in 5 minutes....

Car: 1989 Firebird Formula

Engine: Internal Combustion

Transmission: Completed

Axle/Gears: ones that turn.

He's right....the V6 unit won't directly bolt up to a V8 - the splines on the input shaft are different, plus the internal gearing makes the gearsets weaker.

Engine: 350 TPI, 2.0turbo, 383 in the works, 289-4BBL, 232, A-head 4-cylinder

Transmission: T56, 5-speed, 700R4, C4, T176, semi-auto 2-speed

Axle/Gears: 3.73, 3.90, 4.88, 3.55, 3.54, 7.00

The T5 used behind the 2.8 is junk, and shouldn't be used with a V8, even though it might be possible with a custom clutch. In good faith I wouldn't sell it to someone for this purpose.
