Small block or big block in a truck?

Love the 318, 4bbl, 727, 3.55 gears, dual exhaust, 1976 D100 Truck I have.

Total different truck compared to the slant 6, manual 3 spd that was in it.

Guess the '91 318 Roller Engine with the stock 9.2:1 compression and stock 302 closed chamber heads, has something to do with the performance it delivers.

Who knew Non-Ethanol gas would be $4.00 a gallon today. Sitting good, gets decent mileage.
