[s-cars] how many miles can the AAN bottom end last without bearings/rings?

[David Kase]

Hey Peter,

Spun bearings generally do not ruin a block.  Usually the crank gets 
scored and needs to be turned (different sized bearings are then used).

As for the bottom end, I'm new to the AAN but enjoying the hell out of it.
