No Dave, Chrysler played the HORSEPOWER GAME along with GM, Ford and AMC. EVERYBODY PLAYED THE GAME, Bigger is better. Oh, by the way SmallBlock Magnum heads and AMC heads used this Hi-velocity, smaller valve tech and it seems to work a little better in the brackets, than all out heads for 11sec or greater.
