Full disclosure: My new LS376/495 engine got hot. Not once, but 3 times with boil overs. The MoTeC shows we hit 275 F. But our coolant temp readout never went above 165 F. The sensor is not accurate, and that is part of the problem.

As soon as we saw signs of over heating, the engine was shut down.

No water in the oil. The oil smells like new. No white smoke in the exhaust. And the compression still feels good. We will do another hot and cold compression check.

Any thoughts? Is the engine "cooked"?
