Desired compression ratio
I just read the 411np are minus 14 cc pistons. I also now see they are 1.7 CP so if the deck was zero there is not much chance of any other piston being used. Though if someone uses those pistons I doubt the deck would have been shaved or zeroed out. Ideally I would like to get or build a 400 at least 8.5 to 8.8 compression ratio.
