Did someone say LS427 ? I hope everything goes good for you. When a engine is contaminated with metal such as a nut and bolt a lot of stuff can happen other than the obvious. The motor is spinning at 1,000 to 1,500 Rpm's minimum when it starts and when contaminated. Those noises were your pistons smacking the nuts and bolts till they wedged in something then just kept deflecting till turned off. Then restarted. If you think water in gas is a problem amplify it by a million. Like Tim said cams, journals,bearings,valve guides,springs,etc. The engine is aluminum that nut and bolt are probably some sort of hardened metal. Metal is gonna win. That whole motor should be broken down inspected and mic'd. By the time that's done mine as well get a crate engine. I would only want to go through that experience once really never but cover all your basis. Don't let them tell you what's excepted. Call a machine shop and tell them what happened see what they say. Good luck.
