I am aware that there is a new CP piston listed in the NHRA accepted product list (C3A-CP) as well as number of piston that were added recently.
Diamond and JE have added new pistons to this list. Has anyone had the opportunity to put together an engine using the new CP's or any other piston
for that matter, to determine as to whether or not it solves this problem and still performs well?
