3.8 conversion to 3800

Just wondering if the 87 year 3.8 can be easily converted to the 88 and newer 3800's. Also wondering if the trannys are all the same from years 87 to 89 and 3.8 to 3800. Thanks

Well, they are essentially the same engine, so I dont see how that would be a problem; however Im not sure of the transmissions.
