1969 Swinger 340
Pulled the engine back out and got it torn down, it looks like I may have lucked out as only the number 1 main bearing was hurt. Every other bearing had enough assembly lube on it to protect it, and they look like new. I am going to polish the crank and re measure everything, but fingers crossed that I dodged a catastrophe with thus one. And the used oil pump will get replaced with a new one thus time just in case!
