Danny - thanks for the comment on the Nova...it's close!

The gear ratios in a 200 4R are better, as it has a 2.75 low. But you need an expensive forward input drum to make it live, the shaft breaks on the 2-3 shift. You can reinforce the forward input drum and upgrade the sun gear shell in a 700 R4 way cheaper.

They actually use the rear planetary from a 700 R4 in a 350 to make a 2.75 low gear. I've considered using the TH350 rear planetary in a 700 R4, but never gotten around to it. A low gear of 2.75 or there about would make the 700 R4 a much better transmission for performance use, giving it a much closer ratio spread between 1st and 2nd, and a higher wheel/vehicle speed at the shift.
