[QUOTE="twistedneck, post: 14255033, member: 130159"] I am looking for a set of pistons specific for NA, 12.5:1, 2618 alloy.. everything I see on the shelf including the Mahle pistons has a big ring stack, a lot of extra thickness at the top ring land, and a tall skirt. If I am going to build for NA, I want something that takes advantage of it and is light as hell and looks like a Cup car piston - flat, short, and good for NA - horrible for FI. thinking weight on the order of 300g for a bare piston. Anyone know if Manley or one of the typical vendors has these for a Coyote engine? Here is an example of Nascar type piston, with the super light weight thin wall and low friction design you see on a cup NA only engine.. i'll be keeping my one piston jet to help these stay cool. wish I had more.
