anyone ever installed a t56 6 speed into a 1970-81 camaro. got a lt1 t56 to play with. going behind my 620 hp 406 in my 72

 

Unless you purchase an aftermarket T-56 that has been modified to withstand the kind of power you are talking about I feel you would be wasting your time. I've driven many 6-speed Camaros and Firebirds that are showing signs of weakness behind stock or modified lt1's and LS-1s. I think It would be a lot of work for no gain performance wise. If you were in the 300 to 400 horsepower range you would probably be okay.

 

I think you would be alright depending on your driving habits. There quite a few 6 speed cars running 10s on stock T-56's and couple in the 9's. It would be well worth your time and a great fun factor. Plus there are many upgrade's for the T-56 that can with stand abuse with that kind of power.

I think I read on here that the stock T-56 could take up to 500 rwhp.

 

yea. im doing the swap for the fun factor. that and itll be cool to see a car like mine with that amount of power with a t56 in it. itll be a fun tiresmoker

 

There are hardened input and output shafts available, as well as "Viper" internals (taken from the T-56 used in - you guessed it - the Viper). Probably if you searched the Driveline forum, you might find more info on where those parts would be available.

I definitely think a 6-speed in a classic car would be cool. I'd love to have one in our '73.
