I've used both trans in my ERAs and frankly, I thought the Richmond trans with a 3.08 rear was ideal. The Tremec needs at least a 3:54 or 3.77 to work. I have a Tremec with a .82 in my FIA with a 3.31 rear and I rarely use 5th.

PS: You will also need a bellhousing/trans spacer if you are putting a Tremec behind an FE with Lakewood Bellhousing

Jim-
I have a Tremec in mine with the .82 5th and the 3.31 rear end and use 5th all of the time- doing 70 I am turning right around 2500 rpm. My only complaint with the Tremec- which has been fixed on the newer TKO 600s- is
1st gear. In my trans, 1st is 3.27, which is too low (for normal driving I need to shift by 25 mph or so). I think the TKO 600s now have the 2.87 1st, which would be much better. But other than the 1st gear ratio, the rest of the gears are very good.
