Set of 8 , for a Ford 351C . 4.080" bore , 1.250" pin height , .927 pin bore , dished , weigh 460 gram's each . New , never installed. I got these in a buy out . I would trade for an older 4-wheeler that run's for a pit bike even if it need's a bit of repair . Otherwise I am asking $500 for the set . I called WIseco and I was told they would cost over $100 each to make . Still in Wiseco box. Sean Wolfe sprintman_2001@yahoo.com
