700r4 Behind /6?

The reason the 200-4r is gone is because there are no more rear drive Buicks and GM diesels. The Grand National used the 200-4r which is the highest output of any GM car in the 80's. Buick has a history of using only the best parts in there cars. The GN Buicks even had rearends that no one else put in there "G" bodies. I have seen may GN & turbo Regals run low 11's with the 200-4r and have not seen on 700r4 in a car that ran faster than a 13. Maybe I am a little biased being I am an old Buick guy, but have experienced both trannies.

To me all of the GM trannies are barely worth the aluminum they are made out of now.
