I have a set of Brand New Mahle 331 small block ford pistons. They are flat-tops with Twisted Wedge eyebrows. They are 4.030" bore with a 1.165 compression height to use with a 5.4 rod length., They are the 4032 material and feature the newest thin ring package 1mm,1mm, 2mm so the oil ring does not intersect the wrist pin hole. The pistons have the anti friction Graphol coating and the skirts are coated as well. The box comes with the pistons, wrist pins, locks and file fit ring set. At Summit these are $747, but I will take the first $500 plus shipping. I am set up for Paypal also. [email protected] Ohio City, OH
