The T-5 maximum torque is at 330 ft/lbs. No way can it handle what you are setting up. There are some companies that can custom build them for heavy duty service but they are still not designed for it. You should look into the new Tremec 600 or TKO which will handle and designed for your stroker. The Tremec 500/600 are brand new and replace the older designed 3550's, etc.

I just swapped my motor from a 302 to a high performance 351 and will not have to worry about my transmission choice. I bought a Tremec TKO.
