I grenaded my slant 6

I broke 3 LA's (or they broke under me) but only 1 was pretty bad. 1 was a spun rod bearing. I did nothing to it but run it. It has oil, the oil light flickered on idle but I understand that was not out of the ordinary. Maybe it starved the #1 journal and it seized up and spun the bearing but the rod was done, the crank journal was done and to me the motor was done (original 273-4) so I took everything off that and put it onto a 318 short block. That one lost a rod bolt and once again, the crank was damaged as well as the rod, but I never even checked the bolts as it was supposed to be ready to go. Yeah, young and dumb. Third was a 340 that had a pin pull out the bottom of a piston. Strangest thing: It started knocking badly on the way home from Pomona car show and swap. I babied it but could not take the noise and finally succumbed to pulling it over and calling a tow truck. I got it home and pulled a head and found one piston was about 1/2 inch higher and had some valve scars on it. Pulled the rod and half the piston stayed in the bore. It literally pulled the pin right out the bottom of the piston, broken skirts and all. NO cylinder bore damage~! How the heck? I did window a Cleveland block once. Broke the rod and it literally blew out the side of the block above the oil pan and was still beating around the oil pan until it put a hole in that. I had to shut the motor down as it was still running. It happened 200 yards from my house so I just pushed it home!
