I have a 350 sbc in my 54 and we just put a new Walker Z-Cool radiator in ... same problem; the fan was sitting way too low. So we removed the fan and installed a 16" electric fan w/shroud.

Perfecto! And I can't hear the fan at all -- note: we wired the fan through the ignition so it doesn't keep running when I turn the engine off,
