I have a t-5 WC in my '69 behind a stock re-built 350. I am extremely happy with the combination. The 2.95 low gear paired up with a 3.08 rear seems perfect to me. The shifting is much smoother than the old external linkage was and feels real positive. I know the transmission is the weak link here but I seldom beat on the car and have had more than five years of fun out of it so far. I do have a spare tranny on the shelf "just in case".
