Received a 68 302 (C8AE-8015-B) from a buddy with matching heads that was running. I started to take the motor apart to put all new gaskets and clean it up for paint and when I dropped the oil pan I found the first and second piston on the passanger side had dropped the outer skirts into the pan. There seems to be no internal damage to the block that I can see. My questions are what causes this, and where do I go from here? New engine, or do I just throw in new pistons and rings and run it to death? I am wantind to drop this in my 51 ford shoebox, but a little nervous as this is my first motor tear down and to come across this right out the gate... Thanks in advance guys!
