I think there's some type of misunderstanding by the OP here. The 200r4 is the obvious choice over the 700r4, but if your going '350' Chevrolet instead of 350 Oldsmobile, than the 700 is cheap and easy to find. The olds 350 isnt the same as chev350, so the 200r4 doesn't connect to it without a 'trans-dapt' kit which adds $100s to your build cost. The olds 350 is hard to find some places. If you end up getting a chevy350 instead you will see why the 200r4 may not be the trans you end up with in the end. Obviously finding a olds350 would be the best solution to this problem, rather than having to re-do everything if you go chevrolet.
I must say, I agree with you there. If he does decide to go with a Chevy engine, the 700-R4's are probably more plentiful and therefore might very well be the better choice.that is what I was trying to say but I assumed the OP wants to go 350 chevrolet in which case a 700 might be a better deal, for him. There are a lot of camaro / firebird getting junked around here and not very many g-bodies with 200r4; just saying.
