Charles are these 4032 or 2618? I was planning on using Arias pistons but the ones I've seen are 2618 0% silicon content, they are stronger but they will expand more than high silicon content pistons. This means piston/wall clearance will have to be increased to compensate and I am not sure I want any piston slap on cold starts. Thoughts? Do you think 4032 forgings will support 700rwhp? What are these CP pistons rated at?
