With the help of my fellow VMF'ers, I have found a 351w for my 65 f/b that has, shall we say, "suficient" horsepower...at least for now. The question is for those of you out there that have made the swap from 289 to 351w...What kind of problems can I expect to run into in the swap? I know it's a little bigger than the 289/302 block, so I'd guess that room is at a premium. Did you have to buy anything special for the swap? Advice...?
