Well said John.
Some great things that started for most mfgs in the 80s:
Exhaust systems with a stainless blend that look bad but don't rust out.
One piece rear main seals, since they could no longer use asbestos.
Rubber encapsulated steel oil pan gaskets, to prevent blow out from a little crankcase pressure.
Basic, simple efi for much improved mixture control under all conditions for greatly increased intervals on tune ups and engine overhauls from blow by. Wet flow intake so nothing to clog and a stepper motor on the linkage rather than a port on the tbi of a dry intake to be cleaned periodically.
Roller camshafts with lower valve spring pressure, to cope with EPA mandates on the quality of oil.
I still prefer carbs for toys, basic efi for tools.
Carbs also get a bad name because of all the mods done by folks who do not know what they are doing. Most work well right out of the box and are fully adjustable; even oem carbs once the adjustment screws have been uncapped.
