402 Big Block 4 Barrel dual Ex

How come I can`t get more power out of my stock 1972, 402, dual exhaust,4 barrel, no cat converter, big block. My new Tundra will out run it easy. The motor and tranny were rebuilt 3000 miles ago and the truck runs great. Just not the power I remember and about 10 mpg using premium. Thanks, Joe Watson
