My thinking is that he is compromising some of the street ability he is looking for by using the pistons he has.
In my mind, and I could be wrong but this would increase cost of build substantially? Or sounds like a cam/lifters/valve train purchase is needed regardless. So would there be any real price difference?
I,lol say it again,I do not believe those pistons with a typical Chrysler open chamber will measure 13:1. Secondly, thicker head gaskets would knock it down some more. IMHO
