I am currently building a 383 that will probably exceed 500 lbs of torque at the flywheel. Obviously my t5 is history, but im not sure if a even a t56 will be able to handle it. The highest ive seen a salvaged t56 rated for was around 400-450 lbs. Of course money is an issue for me, but id rather do it right the first time than have to go and fix my problems later. That being said, can i make a salvaged t56 work, or will i have to purchase a new transmission. If so, what transmission would you recommend? ps Yes I have read all the threads on t56 swaps, I just feel that 500+ lbs is on the cusp of a t56 threshold.

MANUAL SHIFT IS MANDATORY!!!!

 

i would say if u can get a used one is a tubo 400 or a turbo 350.

 

Any other suggestions please. I just noticed that those two trannys were automatic

 

six speeds inc. and rockland standard gear can make a t56 that will stand up to that 383 of yours. I had the same issue with the 383 I'm working on, but I went with a 2004r, but auto is my preference for drag racing.

 

you need to get a tremec six speed

 

How much will the those t56 from rockland support. I went on their site and they didnt say how much they can handle. Also does six speed inc have a website because i couldnt find one?
