if its your daily driver and its not in your budget to break it than drive it like you own it , this would apply if the crank was a virgin stocker ,
if you can afford to fix and dont care if this car sees down time , run it like you stole it , odds are something else will give up first anway.

if you cant afford to pay dont play .

Wouldnt bother me in an ungirdled engine. Caps or block will $hit the bed first.

Having the crank turned .010 or .020 makes the difference in the journal thickness about the size of a hair. My engine builder said that it wouldn't make a difference as long as everything else is up to par.

Just have a perfect tune on it and no knock.

The fillets are 0.025 undersize, so turning the crank to 0.020 won't get into them yet, but 0.030 will.
