this isn't a thread asking about the pros and cons of each trans- i just want to know if the mounts are in about the same spot on each type of trans?
i only ask because it's late and i don't feel like driving to the barn where i have one of each type of trans- both of which need to be rebuilt.
i'm getting a solid (but somewhat abused) 86 Monte SS with 2 parts cars (a smashed 84SS and an 85 V6 car)for cheap with no motor or trans from a cousin, and i'm getting a good 350 with a good 700r4 mounted to it from another friend. will the 700 easily bolt to the 200-4r crossmember, and a simple driveshaft chop take care of the install?
my total investment in all this stuff will be in the area of $700, and i want to get it running for as cheap as possible. i want to put a good 200-4r in it eventually behind my 94 Caprice LT1, but having the car movable in the meantime would be nice..

The 200-4R has the rear mount about 4-1/2" aft of the 700R4 mount.

I know you said you wanted to keep it on the cheap but RCG700 from http://www.crossmembers.com/g-body.htm will put a 700 in there without issues

thanks for the suggestion, but i already knew about those crossmembers.
but i don't plan on running true dual exhaust, and if i did need to move the mount, then i'd just break out the spare steel and welder and make it work or do it old school and drill new holes in the frame or something like that.
i wonder if a later model Caprice tailshaft would put the mount in the right place? that's what i used in the 74 and just slid the crossmember back to the TH400 holes on the frame.
i like to think ahead to plan for as many possibilities as possible before actually tackling a project- especially one that i'll be working on 130 miles away in someone else's shop using someone else's tools. that's why things tend to go pretty smooth for me when i actually get to wrenching..
