This Tremec set up was removed from a Superformance AC Cobra with a Windsor. The car and transmission is 26 years old and had 6200 miles. The drivetrain was removed for a new set up and different combo. The transmission shifts great. The only issue is if you try to down shift to 1st year, sometimes it grinds. That's the only time it does it. The clutch & flywheel are like new.
The flywheel is 50oz so good for any 5.0 302 or modern 351.
The car was never raced and clearly the transmission didn't live a hard life being in a super light car.
