Big block, everyone has a small block.

I'll give yah an idea on fuel economy. My old 84 1/2t 4wd had a 350, stock but ran good. Auto tranny, killer 2.73 gears, and 31" tires. Was a dog.

Swapped in a rebuilt stock 454 with headers, 4-speed, 3/4t's with 4.10s and 35s. Of course I had a lot more power, AND GOT BETTER GAS MILEAGE. I drove this truck almost every day. I drove this more than the '08 Tundra that was my dad's.
