+1 more for stock rod bolts being your weakest link against RPM in the bottom end. SBC's are the same deal, get north of 6000rpm and stock rod bolts arn't up to the task.

Bearing and bearing for me. Went through 2 motors after bearing got ate by the crank. Just got the car back yesterday hopefully this one will last this time. Cross my fingers.
