That kit is one of my favorites but I never built one. When Dad was Valvoline racing director Ivo was one of their drivers under contract. Somehow Dad got a factory built Revell Ivo 4 engine. It was VERY well built with some painting done but body was the molded red. Needless to say of all my model building friends I had the best one!!! It was broken and then lost although there are a few parts hanging around. I need to build one. Thx
