you will need to weld in the frame extensions. everything else will just bolt in. be sure to use a donor g-body with a 200-4r. swap the x-member, lines, tv cable.... all that stuff. _________________

I dont think the 85 needs the frame extensions. If you run the stock exhaust you can use a stock crossmember. If you want true dual exhaust there are a few different "double hump" crossmembers out there. The cheapest one is probably "Iceman's" from maliburacingdotcom. Jegs, Torque Tech and I think Summit have some also. You would also need a way to lock up the convertor. Several aftermarket kits out there plus a couple wiring diagrams floating around on the net. Depending on what your replacing, you may be able to use the stock drive shaft.
yea i have the double hump one already brand new in the box here is what my car came with....double hump cross member,new fiberglass side skirts,3in full function cow hood,long tube headers,but i really dont have much money so i herd the 200 was a direct bolt in and i tried to look in that site http://www.bowtieoverdrives.com/index.shtml but i really cant find much info so im trying to find a person who did it to give me some advice if they can but all help i will love lol thanks guys

What info do you need? They came in some Elkys from 85 I believe on up. They also came in other G-bodys. Its the same length as a TH350 with a short tail shaft. It has the tranny mount farther back though so crossmembers will not interchange. Still has a mechanical speedo cable. Same splines on the out put shaft so the driveshaft will interchange between it and a TH350. As for running it with out a computer all you need is an aftermarket lock up kit for the convertor. As for the TV cable. You will need the proper brackets for what ever carb you run so it can be adjusted properly and not fry the tranny up. It can be built to hold a good amount of power. The Buick GN guys run them in to the 9's with the right parts.
thanks you sir...i know my freinds 86 monte carlo ss had a 200r4 in it so i guess i'll just try to find one laying around as for the cross member cant i just do some fabbing and move mine back since i have the aftermarket double hump for the true duel?????

Not sure on moving the crossmember. You'll have to crawl under and see if there is room to move it back. I think there are some frame issues on the drivers side but I can't remember what they are.

if there is another set of holes about 3 inches back further in the frame at the crossmember than the ones the crossmember is using right now then you will be good to go
if not then youll need a 200r4 specific crossmember
i could look under our 85 it has a 2004r in it factory original with 305 engine
im about to get an 88 buick electra estate wagon that runs perfect like brand new, it has the 2004r in it as well with a 307 4bbl i am going ot keep the drivetrain and haul the car to the shredder
in a few days or so
good luck _________________ Randy
