I have the opportunity to buy a outstanding example of a 90 350 sdl. Now I know all the hits on the 3.5l motor, mostly flexable connecting rods, my question is, the earlier cars have the 3.0l motors which are much more reliable and essentially the same block, I believe, could one replace the 3.5l engine with the 3.0l block and the 3.5l accessories, like turbo, injection pump, exhaust, electrics etc, anybody done this? Any reasons why it would not work? Any drawbacks? THX
