T-56 Needed

I have a 85 camaro- getting ready to jerk the drivetrain out and start over. My missing link is a trans., I decided to go with the T-56 6 speed but have yet to find one. I cant use a stock one due to about 600 ft. lbs. of torque, lol. but if anyone can post links for me, that would be great!!!!
Thanks,
Rick
