Keeping it all stock limites your choices a bit.

Keeping it just stock appearing does open things up a bit more. I odn't recall if a '53 1-ton came with a 228 or a 248, but to stay stock the correct one of those is what you need.

Stock appearing makes the 270 and 302 reasonable alternatives, and if it were me that's the direction I'd probably go. My '55 1st GMC Sububan has the 270 and performs real well with that motor though the original motor was a 248. These motors would be basically a boltin swap.

It's true. I really don't do anything but browse the Internet looking for trouble...
