4.155 bore, 1.270 pin height, works for 4.375 stroke with a 6.700 rod. 20cc dish so at zero deck with a .030 gasket roughly 10.8 or so. Have rings, oil ring support rails .990 pins all new in box. There's a set of Eagle h-beams new in the box, 2.200 journal They don't have fancy L19 bolts, just the standard ARPs. They don't have to go together. I'm not sure how close I will get to what I paid, not sure what custom Diamond pistons sell for. If you think you might be able to use these, I can send you some pictures, or more info. Thanks!
