Saturday I wen to a great car show in Lampasas Texas. The turn out was great for the old cars and trucks. While driving there I noticed the truck loosing power because 60 mph was hard to keep. After the show I was driving home and I couldn't keep 45 mph and the temp was rising in the engine, then all of a sudden something let go and the knocking started. All the valves are moving, nothing sticking out the side, no water in the oil and water is in the radiator. So I had to stop ad get trailered home. So now I have to go into the engine and see whats going on in there. Hopefully it is something easy and I don't have to replace the whole engine! If I do I guess a V8 swap will be next.
