Still running one in my 67... Good little engine and cruises the hiway just fine. The V-6 ran through 69 in the gmcs.

These are industrial grade engines. They are tough and torquey, but thirsty! I would keep it if you are not daily driving it.

More heavily advertised in the early 60's when typical buyers were more interested in engine durability, versus later 60's, when buyers were more interested in performance.

Re: 68 GMC with 305 v-6 ??
Probably one of the most overbuilt engines ever installed in a light duty pickup. A V12 version was built off it. Cool and unique to see one today.

They're indestructible... unless someone leaves water in the cooling jacket and it freezes.

Re: 68 GMC with 305 v-6 ??
Thanks guys. I just pulled it out !! I’m installing a350,350,p/s, p brakes. It’s complete from air breather down. 3 speed std. I have all the clutch linkage , z bar , bracket. Motor stands I have a video of it running. Not sure what it’s worth. Thanks again.

Re: 68 GMC with 305 v-6 ??
It's definitely worth finding a good home for. There is a following and as said, an overbuilt and durable engine. Would be a great swap into a tractor
