I just bought a 426. After i finaly get the SOB started almost imediatly it starts dumping cold antifreeze on the floor and the gasket in between the slip on pipe and the head pipe starts smoking. So I frantically run around trying to figure out where the antifireeze is coming before she gets too hot. I couldnt tell so i killed it. Now theres a puddle of antifreeze directly below the engine and i cant tlel where it came from or why. I dont understand, it ran fine a week ago for several miles.
