I was thinking of doing the 351w swap into my 89 hatch...I want to build up a 351 engine and I was wondering what block is best to use? I want to go with a roller block, is that a good choice and why? How can I determine the difference from a non-roller bare block and a Roller block other than just the engine code or whatever, like what other physical differences are there? I have read that the 92 blocks are capable of using roller cams is this true and if so what would have to be done to it to allow it to use the roller cam? Would that be wise to do? My last question is why cant I use a 351w computer with this swap?
