trying to identify aftermarket 340 Pistons

I use to sale him cores. Untill he screeed me out of over $1200. He can go to hell for all I care. Very unchristian of me but maybe I might forgive the greedy sob someday.
You go right ahead and keep on dealing with him there will be a day when he breaks it off in you. I have no doubt. Unless you keep paying him that'll what keeps him happy.
