damn, this thread has crazy stuff in it. First off 3 qts below max is catastrophically low and I'm pretty sure your engine is toast if you took it to redline. What you had was metal to metal contact inside your engine without anything to lubricate the parts.

Second, 7.8L is the size of the windshield washer tank, not the displacement on the engine. If it were 7.8L I'd hope it have at least 700hp to boot but it'd prob only get 5mpg.

Lastly, good luck dude. Time for a new motor or rebuild it sounds.
