Run the th350 with the 700-r4 first gear in the th350 case. Put 3.23 or 3.42 in the axle but you need a strong engine if you plan on running it at the track.

stick with the 200-4r, but see if you can find a GN, 442, or monte SS version in good shape. and make sure you adjust the TV cable correctly!!!!!!!!!!!! i can not stress that more. the 200-4r got a bad rap mostly due to people not doing it right.
if you go with a 700, which statistically had MORE issues than the 200-4r when stock, the acceleration will be great in first gear and then DIE. there's a huge gap between 1st and second, the 200-4r is much closer. the 200-4r also has a better overdrive.
(BTW the 350 is a great trans, but it's not worth it to swap over to one and lose overdrive, unless you're on the strip)

and like somebody up there^ said, a well built 200 isn't much money. if you get a 350 or a 700, you just sunk in a bunch of money. what if the trans is bad? (i'm assuming you get a cheap trans--it's what most people do) now you need a $1000-2500 rebuild anyway! it's more cost effective to get a well built 200-4r and not have to change anything.
and let's remember the 200-4r was used in the GN, GNX and there are a number running 9's! (modded of course)
if you do a search you'll find this argument hashed out MANY MANY MANY MANY times.

That's a horrible idea. The gear spread between 1st and 2nd is bad enough in a 700r4. If you used the first gear of a 700r4 with the second gear of a th350 the gear spread would be even greater.

2004r no doubt. Honestly in todays day and age of upgrade parts and easy net availability theres ZERO reason to run a 3 speed.

Any th350 is going to be built anyway to handle decent power so its not like you can even take it out of the box and be ahead of a 2004r

The only place that th350 and 400s have a place anymore is in a strip dedicated car or tow rigs
