Getting ready to box the frame on my 1958 GMC Suburban Carryall so I can mock-up the 454 big block and 700 R4 trans with the mounts. I have four-cored the original radiator, but I'm unsure whether or not I need a fan clutch. I'm not putting in air conditioning,so is the only issue noise with a constantly running fan, or is there also a cooling concern with no fan shroud?
