    If they had forged rods or better rod bolts this would not be so common.

    Dang! Didn’t you have another one that threw a rod thru the block? What a run of terrible luck! So sorry to see this ...

    I knew a guy who owned a 1968 Dodge Dart with a 383. One Sunday he and friends decided to do an oil change while drinking beer. Afterward he started it up and went hot rodding, engine started making ominous sounds so he drove it back to his place to check it out. Discovered that he and friends had forgotten about the 2nd part of an oil change--to put new oil into engine after draining old oil out. He was mad at himself I guess and decided "screw it" and fired it up, still with no oil in crankcase, and put the pedal to the floor until it had a catastrophic event.

    I got a story. I met a girl driving a 68 GS. Saw her around town a few times. Finally had a chance to meet her father - yet when I arrived at the house/garage there in alley was the block looking at intake valley the block was almost split in half.He got to talking about racing the Buick back in the day.430 bored out manual body Turbo,etc. This guy said he beat kenne bells car back in the day. Anyway the girl was cruising down 80/94 and run over something knocking pan up against pickup.... He had oil pressure gauge mounted in clocks spot. But he said she hadn't noticed it

    Another pic, driver's side. You can basically put your arm through the block. the lower rear portion of the block broke off on both sides. cam beat the hell out of the flex plate when it ejected and put a dent in the converter and sheared 2 bolts. The angled piece under the "0" at the back of the block, (lowest driver's side bellhousing bolt location) fell off. The entire corner fell off. I'm thoroughly surprised the transmission isn't damaged at all that I can see, besides the converter. Can still turn it over too, still has compression on #1, 3 and 2. lol

    AND IT WAS STILL RUNNING.

    It’s not the strength of the engine internals that’s the issue it’s the lack of clearance between parts. A bearing issue on a rod leads to the rod hitting the cam and then we see these damages.

    I posted a pic the other day of a 350 engine that had valve to piston contact because of a failure to properly degree the cam. These engines leave no margin for error, a bad timing chain can lead to a ruined engine. And it’s not an easy rebuild it’s a start fresh with all new parts deal!
