Ok, little update. Ripped my 5.0 out and completely dismantled the whore.....nothing major wrong with it. Took everything out of the engine bay and had it checked or changed....nothing wrong with any of it. So...I have come to the conclusion that...its just a worn motor, they guy who had it before me drove like....well like i want to drive it so its not a huge shocker. Looks like im gonna cough up around 7,000 and just build me something with around 400 hp and go from there.
