bigbadswingdaddy, the water pump from a 216 will bolt right on a GMC engine, I have done it several times. Aricheson, see if yo can find a core support from a GMC, the radiator will be positioned right. Front motor mounts will be a bit forward of the Chevy ones, I used F**d stock length spring shackles as spacers, they are just the right length. Everything else is a bolt it.
