Does anyone know what the original cooling system was on a 67 396 or 427 w factory A/C? Was the fan a 4 or 7 blade, was it a clutch fan and was there a factory shroud? I got one with dual electric fans & it seems to run hotter than I would like. Thanks.

Should be a 7 blade clutch fan with A/C and a BB. And a shroud no matter what engine. What core size is the radiator? (thickness)

Remember, a fan is only helpful from idle up to 20 mph. If it gets hot constantly you may have other issues.
