Jeep Strokers

I'm ball parking around 250hp once the wrenches are put away. I know these Trans's aren't exactly bulletproof but will this this hold up okay as long as I'm not shifting at 6k ?

I raced a T-5 with almost double that horsepower for a couple years.

Was it a wc or non world class though ? Granted the nwc max torque is like 248 and wc out of the box is 300. Fifty pounds of torque difference isn' much lol
