Okay Just reread this post...
Ya'll know I put the 700R4 in a while back and I'm unhappy with the performance as far shifting. Reading this thread makes me think the problem might be that the gearing in the 700R4 and the stock rear rations might be too close?
Am I just babbling? I'm guessing it's still the 3.55:1.

your 700r4 has 3.06, 1.63, 1.00 and .70
so your launch ratio is 10.863
should be pretty good.
OD final ratio is 2.485
what about your shifting dont you like?

Vette(s): 1977 L-82 originally white/buckskin interior.
Currently undergoing a frame-off resto. and modifications.YEEHAW!!!
I had the Super T-10 with a 3.70 final drive. The 1:1 ratio in 4th gear gave me 4000rpm at 80 mph. That's too much screaming for highway speeds.
I'm currently in the process of installing a Tremec TKO600 in my never-ending rebuild. I'm counting on this to take that "problem" away.

Gribble, If I could do it over, I would do exactly what you are doing. Your rpm's are supposed to drop off about 33-36% off the 4k at 80 or 2680 - 2560 plus your first gear is much better also!
What are your plans with your t-10? Are you keeping her or selling off whole or in parts. I ask because a buddy of mine is putting a t-10 in his 59 vert and needs a BW shifter.
Let me know what you do!
Thanks, Rick

Hard to explain...Just doesn't feel "right".
I am on the other hand running about 1800 RPM at 70 MpH.
I'm also getting a sound like something is slipping. I dunno, I just need someone else to drive it and see if I'm losing my mind.
