Parts needed to change v6 T5 to V8
I have a V6 T5 trans and would like to rebuild. I want to change it to fit the V8. What parts are different. I know the input shaft is different, Is that it?

The gear ratios are different and thusly from having a higher (first) gear, it's inherently a weaker trans.
You will save time and money buying a V8 WC T5.

lets assume you dont have enough money for a v8 trans but need the v6 t5 to match with the flywheel of a 350 tpi. what should i do with the clutch matching problems. the v8 is 23 splined and the v6 is 14. is there a clutch to match the two?

McLeod has one, heard that centerforce may have one, Medatronics (www.gearzone.com) definitely has one

thanks for the info. centerforce had a kit but it was way to much money. 400 bucks for the whole kit. medatronics has a clutch disc with the 14 spline v6 and it is 10.4" like the v8's. my next question is should a standard 10.4" pressure plate and throwout bearing work. those i could probably get cheaper around here. although the centerforce pressure plate sounds nice with centrifugal weights attached so there is more clamping force at higher rpms.

the standard pressure plate and throwout bearing work. I don't think you need a centerforce plate unless you're running a really powerful motor, and if you're running a really powerful motor, then a V6 T5 is seriously inadequate. I would just go with a stock pressure plate. (Wait a sec... I DID go with a stock pressure plate. 
) Just make sure if you get a used one that it isn't worn out or discolored or has heat cracks or broken springs or anything like that.
Also note: the V6 T5 has a much wider gear spread between 2nd and 3rd gear (e.g., the rpms drop more.) This tends to wear the third gear synchronizer more than a gear box with a closer gear spread (like the V8 T5). But first and second are a little bit deeper reduction, so you come out of the hole a little quicker.
