I would be more worried about where the shavings went, unless this happened not on first start but when the crank or the main caps let go? If that was the case then I would expect to see more damage? Why not take it apart and put it back together after a little light grinding and heavy cleaning? Make sure there are no cracks from the point of impact. Unless maybe there is more metal missing than it looks like? I'm no pro engine builder, but I've blown up plenty of junk! Good luck

I don't know , if that is a FORGED crank , which it looks like , then that would be normal look of the way the counterweights are ground to size , not all counterweights are the exact same shape and machining marks will not be the same . If that was ground down by hitting the pickup tube I would think the tube would have a hole in it by now given the amount of area that is flattened . Quick check to see if you had a lot of metal go thru the motor is to open up the oil pump , if it was sucking metal you would sure know it by looking at the coverplate .....

What balancer does it have on it ? Do you have a vibration problem you are chasing ? Yes assembly date. Has an aftermarket balancer. No weights Had a vibration, but found a real loose pinion nut. Which pretty much happened all of a sudden. Which is why I did not think it was engine related.

I'm thinking someone used the thinner oil pan gasket and that's what caused the touching. I picked up the thicker one.
