i am doing a 400 in my 82'bird so i need build up advice and i also need to know if the t5 can handle it.

i have a stock t5 trans behind a 576hp 434sbc. so far so good. the biggest problem is traction. my car doesnt hook. if it did i would bet that it would destroy my trans

I had the same concerns you do lockdun1, when I was thinking about swaping in a T5 behind my small block. I did some research and found it is not always the internals that break, but it is the cases that break. From what I can remember (some one correct me if I am wrong) but the Non-world class cases handle something like 200ish ft/lb of torque while the World Class cases handle around 300 I believe.

I gave up worrying about breaking a T5 and put a built TH350 in, its a WHOLE lot cheaper and I have no problems out of it, and I can dial the car in for the track a lot earier with an auto than a man because of all the shifting variables.

My 2 cents, put a built auto in and you will not be disappointed.

However if you have the money, there is a company that can built up your T5 to handle somewhere around 600 ft/lb of torque, but it costs oodles of moola.

thanks i will consider u alls input i also was considering the 350 but i already have a 1995 camaro whith an auto so i want a manual car and the t56 is like a grand so the t5 does sound better.it wont be a drag car it will just have a rebuilt 400 and the edelbrock top end kit hope i dont brake it.+i do belive i can use the stock bellhousing so it would seam easyer.
