I was talking to a guy that has a '52 GMC 1/2 ton that currently has a 235 in it. He said he took out the original 216 a few years ago. I told him I'd never heard of a GMC coming from the factory with a 216 and he said his granddad bought it new in Greeley, CO and he still has the original paperwork on it that shows a 216 engine.

So my question is: Has anyone heard of this "economy option" (that's what he called it) and how many came that way?
