I think a great deal of this has to do with fuel injection systems rather than carburetors. There is much less fuel blow-by in modern fuel injected engines than there was with carburetors. This blow-by resulted in fuel dilution of the oil and greatly enhanced wear on the main bearings. It wasn't uncommon to start hearing bearing chatter at 80-90K miles, whereas nowadays with fuel injection and improved engine oils, the bearings seem to last far longer.
