Re: 700r4 Real axle ratio

Correct reference to relative gear ratios is the use of "Long" vs "Short". Derived from the racing world meaning long race track or short race track gearing.
So a 2:1 ratio would be for a LONG track while a 4:1 would be for a short track.

But just exactly why does lugging an engine wear the main bearings??? Because oil pressure has dropped or what???? Just about any 'abuse' of an engine that will knock out the main bearings will ruin the rod bearings long before any main bearing symptoms would ever show up.

I just looked at the 56 Packard SM. The mains get oil BEFORE the rods.
