Rob, if you still do the FaceBook thing might want to look up Edward Miller. He just set some records at Dragweek. Granted, they are a very high $ head he used but they also flow like a tunnel, Predators. He made enough power on his big cube/Predator headed wedge to push a Duster into the mid 8's....on pump gas. I seen on one of his FB posts where he made mention of using 87 octane pump pee pee. Kinda makes one wonder about compression....
