I Need Help With A Math Problem

If I remember correctly, the 350/360 as rated at 390 or 400 HP back when we raced on street tires, around 1973. I remember that because nobody was racing them because of the HP rating. The '69 Z/28 302 is rated at 309 HP now and to race a '70 Z/28 which is rated at 320 HP, there is 110 LBS difference between the cars with the '70 having 48 cubic inches more with the same engine manifold, carb and heads. It's one of the biggest loss of power than any other engine combo.
