What do I need for this tranny?

[Pendy 0]

I am wanting a C6 for my mustang that will hold up to the power of a 427W. I was thinking something along the lines of the one featured here (third one down) http://www.broaderperformance.com/c6_transmissions.htm . However, I know that it is cheaper to build one yourself. What parts would I need to build the 500hp Stree/Strip - Wide ratio C6? Also, do you think that it would hold with the 427W?

I would highly discourage buying a C6 they gobble up so much power it is ridiculous. My car used to have a C6 and I hated the thing, it will have atleast 25% parasitic loss from the flywheel to the wheels. With the kind of power you are running that is 100hp or so. You can get a built C4 much easier than a C6 with all the benefits of the C4. You could even go AOD if you have some more cash, and would like more streetability.
