13.3's to 11.8's to Forget it...

Let me just say to the few "nay-sayers", if I don't make it, fine. But I've been told a stock 360 without headers and 2.45's couldn't go 13's, but I went 13.9's consistently. Headers and 2.94's and I'm down to 13.3's. I'm going to change the 4 components (heads, cam, converter, gears) and see what I can get.
P.S. - boost or bottle will not be used.
