QUOTE=Dova;2375590]what is the difference in the 200r4 and the 700r4 besides losesly being based off the 350 and 400?[/QUOTE]
The 200 was the overdrive for the Caprice and other full size GM cars . The 700 was put in the trucks probably the van also, not sure though.
I think the most popular seems to be the 700R4 conversion. There are a couple of write ups about this in the Faq forum.
