What type of tranny?
 

No no you sicko's I'm looking to replace the transmission in my 86 TA currently has a T5 in it with about 55k miles on it and no issues but I recently made a heart transplant and replaced the torque monster 305 LG4 with a more fuel efficient 383 stroker, looking at around 475-500hp to the flywheel and similar torque numbers, rear has been updated to support it but my guess is its only a matter of time until the trans goes kablooie. Any suggestions? T56? Def want to stay with the gears.

Thanks

Keep it stick. Get a T-56.

Yea, T56 swap is likely your best bet. It's been done plenty of times, swap parts are available all over.
