Might want to do some research on what the so called 600 or 600 wt lube is! It's normally SAE 140 gear lube (which is what Ford called for) repackaged. 600W was a brand name Mobil used for a steam engine oil. Mac's claims there "600w" lube has a viscosity index of 2270, which places it in the middle of SAE 140.
