I'm going to bore and stoke my ZZ4 crate to a 383, but I'm slightly confused on which rotating assembly to get. If I bored the engine .30 over would actual engine CID be 383 or 380? And what would include .30 over pistons and rings right? What about rod length and engine stroke? I'm ordering through Summit and those are the questions I don't know the answer to, in order to make sure I'm ordering the right parts.
