Rebuilt 340 knocking sound

You would be amazed what a hot tanked and never started rebuild will look like inside after sitting for 1 1/2 years.

Especially when compared to something that was pulled out of an engine in use from say 50 or 60 years ago and left to sit in the corner like a slant crankshaft I have...and it doesn't have a speck of rust on it.
