I have a 66 Burb with a 292 in it, and I repainted the engine the medium green color (don't remember name), which is what I found on it, plus what I was told here. Last weekend I looked at a 66 C30 Panel (Ambulance) that is for sale, and it has a 292 in it. The engine was a dark blue color, and on the front passenger side of the valve cover, it had a sticker that said "292 High Torque". Did they use a different motor or paint scheme in the C30 versus the 1/2 ton? I will list the vehicle in the for sale section tonight, no time now.
