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.

Thanks much for all the input on carb size,I really appreciate everyones help. Allen R, from the tel con we had a few months ago you probably
remember that I am an old stocker racer. Since when can you run an
aftermarket carb in stock and s/s. I believe you said something about a quick fuel unit ,just like you use in todays class racing? ed

Eddie, Quick Fuel has had at least 3 of their street/OEM replacement carburetors approved for Stock and Super Stock. Much the same as some of the Weber/Edelbrock Q-Jets were approved a few years ago.
