Isn't the IH V-800 engine supposed to be metallic blue.
I know the picture on the box side for the 4300 shows the engine red but those pictures are a carry over from the previous F-4270 kit wich had a Cummins V903, if you look closely it reads 903 on the valve cover, and I read somewhere that IH made Caterpillar, Cummins and Detroit Diesel paint the engines delivered to them red but when IH developed it's own V-800 came they painted them blue to distinguish them from the other engines.
