Yesterday could turn out to have been a very bad day...



I need ideas where to start. First a little background. I was out doing some WOT runs, 3rd gear 120 mph+, and it shut down. I mean shut down dead. Reduced Engine Power displayed, I coasted to the shoulder and tried to restart, but nothing. All electrical systems appear to operate fine. Starter "clicked" when I tried to fire, so I thought it was the battery. Got a jump, nothing. New battery, nothing. When I crank it, it responds with a "thud". Got one code, P1516, but I think that was from draining the battery & trying to restart.

No smoke, no parts blown through the side of the block. The only sound it made was a screeching sound before stopping.

I tried to turn the engine over via the crank bolt, but it won't budge. Seems locked up or something. Where should I start?

I think I feel like
