For those who are interested in this conversion, I've done a lot of research on what it takes to put a t5 manual transmission into a 65/66 with automatic. I thought I'd post it here.

Gear ratios:
T5 3.35, 1.94, 1.34, 1.00, .063
T5Z 2.95, 1.94, 1.34, 1.00, .063
Tremec 3.27, 1.98, 1.34, 1.00, .068
AOD 2.40, 1.47, 1.00, .063
C4 2.41, 1.54, 1.00

Have you done the conversion yet? I have a similar set up to yours, e.g. Edel performer, 3.55 gears, etc and really enjoy driving the car. I also have a Center Force dual friction clutch that works great!

I have not. It was my next upgrade, but my wife and I decided to have a baby, and she wanted to stay home and keep it, so some of my hobbies had to go. I had to sell the car. (sniff, sniff)

Your 5th gear ratio for the T-5 should be .68, not .63
Only the T-5Z had the .63 gear ratio.

Been there - done that! My parts list is a bit different. Let me say that 3:50 rear gears are about the tallest you'd want. Very much like 3:00 gears with Toploader. Although I like my combo, performance enthusiasts should consider 3:89 or ^.
