I don't know about sour. lol I felt bad for the guy I was helping sell his parts. He spent a lot of money to do this & he didn't even make a 1/4 of it back. I will be posting some of his parts on here, FABO Don't get me wrong, I had a good time. Meeting & talking to people. Most people were looking for B body & big block stuff. O I never noticed this before but I love the POKORNY ENTERPRISES
