i have some other threads on here, i recently had some head/gasket issues and will not be fixing my v6. so im looking for all the information i can find on v8 swaps, also there is a donor car but it is a v6 as well, it does have the manual trans and i would really love to get my hands/feet on one of those and get it into my car. any info would be appriciated

Don't waste your time. Grab the pedals and wiring and leave the trans. there. The T5 is not rated to live behind a 5.7L LS1 and the V6 gear ratios make it worse.

Yeah I doubt the T5 would be able to handle a V8 for very long. Like jmd said the gear ratios would kill you too.

The V6 t5s are rated as low as 200ft/lbs, it has a BOP pattern bell housing, and I've heard even the trans 4 bolt pattern wont even bolt to a V8 bell housing.

damn, thank you very much. grab pedals, wiring, and interior pieces then. thank you much. anything else? all info is greatly appriciated. my 2000 v6 just crapped out, the local salvage yard has a 99 v6 model with manual trans, engine missing though. i have been getting mostly interior parts but will be checking on the wiring, im sure the pedals are still there.

Are the V6 trannies really weak? I was thinking of getting a 3800 car and doing some minor bolt-ons to it and have some fun but I might just got for a Z if the trannies are really weak.

Yes, they are weak.
Get the V8.

In order to create wider gear ratio spread (4.xx first gear in an old 1980s V6 T5 vs. a 2.95 first gear in a 1980s V8 T5 for example,) the gear teeth are changed such that

• either 1st drive/driven gears are reduced/increased in dia. and tooth count
• or the main drive (input to countershaft) are modified similarly.

Any time a pair of gears are closer to each other in size, they are a stronger gearset, all else being equal.

I know of someone with a T56 adapted to a T-3800. Anything is possible and adaptable. However, when you can pick up a good used trans. for a few hundred $, it doesn't make sense to spend much more $ adapting something unless the life of it is significantly reduced.
