The T-5 is/was a Borg-Warner trans. Early '80's non-World Class trannies were rated at 260 FPTQ. A hot V-6 would blow it up. Tremec's, although actually a truck trans, were lifesavers at the time.

BW over the years beefed up the T-5 to its current T5Z configuration, rated at 330 FPTQ with 2.95 first, as opposed to Tremec 350 FPTQ.

With the Tremec, you're stuck with the 3.35 first gear. Mustangs need that running 2.73 rears. Cobras running 3.55 and 3.73 rears don't. Feels like winding and old VW beetle out in first and only going 15 - 20 MPH. Most Tremec owners short shift to second pretty quickly.

Discussed this with Liberty Trans: T5Z vs Tremec 3550. He suggested the T5Z and a good shifter. Used the Hurst. Have been very happy with this setup, now with 15,000 miles on it. Very smooth shifting, and gears right where they're supposed to be. If anything, first could be a little tighter, say 2.65 - 2.75.

Also opted for the billet steel flywheel, Centerforce clutch, but stock bellhousing.

That being said, I had to, and you will have to make a serious assessment on how you intend to drive the car to determine how to configure it.

Mine is a not very tempermental sports car, daily driver and comfortable touring car. My wife can drive it. It's not by any means a race car. But I built it the way I wanted it.

Had I weekend warrior aspirations building the car, my component decisions would have been altogether different.
