70 LT-1 bottom end pics. (What the hell?)

That is the counterweight on the crankshaft - which still doesn't explain the blue paint.

Ah!! The stamp "H" probably means something also.

Crankshafts often have liberally daubed-on "inspection marks" of various colors.

Thank you sir.
I had seen it on con rods, but never noted it on cranks, though it is highly likely I wasn't paying attention at the time I was knee deep in cranks 30 years ago. At 20 years old I was ecstatic to be a helper 2 days a week in an engine shop where our only clientele were class racers willing to do anything with in the rules as they were currently written.

Dennis
It took me a long time to notice this picture. Is it your damper? The color is not what I would expect on the subject Corvette.

Terry....
I assumed that was factory mark paint. When I posted that pic, I wondered if someone would explain the "H".
Couple of pics of a LT-1 crank with paint markings. Not mine.
