I was looking into doing a split head conversion from my 98's single port. My original plan was to bore and stroke to a 4.3 and get the SSM powerpack then turbo it. But I really wanted a supercharger and I saw the Eaton M-112 adapter but it only works with the split port. So now I still want to bore and stroke the block but now if I were to get the split port powerpack what else would I need? Which sounds like a better idea? Thanks!
