knock in engine

I heard that squeek-squeek one time. I pulled the car into the garage and went over it with a stethoscope. Engine was idling.Then it just quit. Pulled the pan and found #2 rod bearing was sticking to the crank and finally spun in the cap and locked it up.
Thats what happens when you run the crap out of your 340, while 2 qts low on oil.
