My 451 made very similar power on motor and spraying it. Smaller cam, more carb and a better (I assume) n20 tune up. Pretty cool to see the numbers somewhat align 30 years apart.
And before I put the BV 906's on which is all I changed it made around 460, totally stock 1968 440-6 motor,+cam/carb/intake/hdrs of course went from a best of 119mph to 125NA and then 133.9 with spray@3300lbs@the line. Plan was to up CR to 12:1 min, never happened.
