    Any chance it might have driven through some water and sucked some water into intake? I know there was a ton of water in your area a short time ago.

    Also, the video in post #2. It looks like a spark plug wire might be disconnected?

    Oh-Oh; I've heard that a time or three and it was never good. One of my slantys put a broken rod right out the side shortly after and became a 5-cylinder.

    I remember a /6 car came into the shop a long time ago. It was making a weird noise and customer said car will hardly move. The engine was running when it drove in. The tech assigned got car pulled into the stall, barely, and turned it off. Now when you hit the starter, you can here the starter turning but engine wasn’t moving.
    The crankshaft broke between last main bearing journal and flywheel. When running, there was just enough friction to turn the back half of crank/flywheel. But not the other way around.
    This doesn’t help the OP any, though.

    I will re-ask my question:

    Yes drained 2 gallons of water but never cranked it just drained put oil it was water in the trans also. I'm pretty sure it was in Harvey I got it after and drained in February and didn't get it running till 3months ago was driving perfect till the trans was not wanting to go but then I had to rev it a little then the knock came but I'm rebuilding it with another block and keep this ass backup but the camshaft has good lobs but it deteriorated on the side a little rigged will I need a new cam
