Re: 1960 GMC K1000 4x4
Kro--they do run hotter than a 350 but with a good rad it should be fine. on the 400 the center cyl's are like Siamesed so no water flows between them, something like that. I ran one 406 in my Nomad for a few years before i went big block. I liked that eng 406 better than my BB 468.
