i just picked up a 62 1/2 ton a couple of months ago. advice i'd give is to go 64 and up, it seems like alot of the catalogs skip 60-62 on alot of parts. and the windshields are a little cheaper if it needs replaced. my six cylinder 235 only gets about 12 mpg. it tops out at 70 mph freeway and is screaming.. i'm guessing a 350 would get about the same mpg with more hp? have a look underneath and make sure the frame isn't bent and check for rust. cab corners floorboards, actually what i would recommend is picking up a book called "how to restore your chevy pickup". flip through it and i think you will get a really good idea of what you might be in for. also it will give you a good idea of what to look for in your potential truck. whether the wiring has been updated-rear end gearing-part interchangability, and what might be trivial and what might be serious. i love my truck but i wish i had read that book before buying it.
