Well, another season has ended with these same pistons and I got a third place finish with them. I have new Diamond's on the shelf for the freshen this winter care of RyanJ @ SDSS. The pistons made it another 191 1/4 mile passes and still holding strong. I'm starting to get a little blowby so I think it's time. Once again, I'm not gloating, razzing, or anything. I just promised I would update if something went wrong or when it was time to switch...
