I'm working on my 455 buildup but still needing some answers. At how much valve lift would I see an interference problem with the 10:1 sealed power forged pistons with a zero decked block, if I were to zero out the block?
I'm looking to hit 10:1 with AL heads and give 450 hp streetable and pump gas. also what rocker ratio should I be using? I have a set of stamped steel 75 ones and would rather not replace them however, If i need to I will and what ratio are the 75's I know a lot depends on the cam but I want to have the options open for any decision.
