A few months ago a friend let me know that a car I sold was abandoned at local school. Thursday, I finally got that car back! Problem!! It has a 440 with tunnel ram and dual 750 Holley carbs, I built the motor 10 yrs ago and was always worried about the engine getting too much gas. I was told the son of the now previous owner had hot-rodded it until he blew up the engine. I think it had an internal explosion where the fuel built up in the oil. I looked at the valley pan and its raised up about a half inch. I checked oil, its black but free of water. I think engine may be froze, but not sure. There are no holes in the block. It blew all the water out all over the engine and it looked like muddy water. Not sure what to think, I haven't torn into it. Anybody have an ideas what could be wrong?? Or if the engine can be saved or is it toast??
