Make me an offer...I have one new, unused Ross piston for a 455 Pontiac...see picture for technical details on box from Ross Racing Pistons. It was a spare I had for a 455 motor using a 428 crankshaft. I undercut the rod journal .050 down to 2.20 inches (BBC size) and used a 6.7 inch rod. Normally you have to buy a entire set (8) of these, so finding one is difficult. These are specially made by Ross for Butler Racing which is where I bought a set. Buyer pays all shipping and handling costs. Check or money order OK . CASH only if picking up locally. Due to spam and crooks, please email me thru Craig's with your cell # and I will contact you.
