To swap or not to swap....that is my quesiton!
Ok....my tranny in my car has lost 2nd gear so I'm getting ready to replace the tranny! I know where I can get a rebuilt 700R4 with 1 year warranty for about $700!! Here's the thing tho'......I found a late 80's model Camaro RS that has a blown 2.8 multiport engine and it has a 5 speed in it!! He only wants $500 for the car so I was thinking about maybe buying the car and taking the 5 speed out and putting it in my '86 TA and saving approx. $200 over buying a 700R4!! It has a brand new clutch plate and shifted great (when the engine wasn't blown)!! Should I swap to the 5-speed or just get the 700R4!??!

Dude if you put a v6 T5 behind that 355 your building, you will be driving over that thing when you hit 2nd gear 
I wouldn't waste my time.

You will need a V8 bellhousing, flywheel, clutch assembly and a believe a different slave cylinder. The V6 gear ratios are more for economy and the torque rating is slightly lower on the V6 trans. If you found a V8 parts car it would be worthwhile IMHO.
