‘78 Chevrolet Silverado. 454 engine w/ th400 transmission. Engine might have a failed head gasket, or coolant system needs burping. Truck is not overheating. Fires right up and sounds healthy. Was a strong runner. Fix it or part it out. Does have dent in passenger side door from being hit when it was parked. Also, steering column was damaged when someone attempted to steal it. Clean title in my name.
