72 Scamp Street/Strip Build. Looking for some opinions and combos

At 3100pounds and sealevel, that calculates to 350 hp, for superstock suspension.Doable for cast-iron heads.
At 3300 you'll need 375 hp, getting tougher for a 360
At 3500 you'll need 400hp and good thing it's mostly a racecar
As you can see, each 200 pounds translates to 25hp , or another way of looking at it is; every 8 pounds costs you 1hp ; start dieting,lol.
Happy HotRodding.... wish I was 19 again.
