I was wondering would it be possible to put a 3800 out of a 1995 Buick Regal into a 1987 Buick Regal? and also make it Rear wheel drive with a 5 speed manual trans.  

So does anyone think it will work OR bad idea and don't even try it? I have the 1995 Regal because it was my brothers and he got rear ended and is not fixable. The 1987 Buick Regal limited has the 231 V-6
Non-turbo with a hole in one piston, the Original Idea for the 1987 was to find a Cheap Buick 350 from a 1970's Buick and use that, I have no Idea for sure on what to do.
