Guys, you don't need more than 400 cubes on a sb Ford to beat up on most of the FE crowd. The aftermarket heads for the Sb flow much better than the BB FE heads. Only two manufacturers that I know of making FE heads. About 8-10 making sb heads. Don't forget we are only moving 2500 lbs not 4000lbs that those torque producing BB were designed for. I have heard that for Road Racing (my hobby) that less torque but higher rpms is the way to go for faster lap times. Leave the Big torque Big cube motors for the drag strip where they belong.
