Suburban engine question?????

[66 lwb cs]

Hi does anyone with a 1966 chevy suburban have any motor pics? What I am looking for specifically is the original color or the block from the factory. I have a 66 C20 CS that came original with a blue motor. I know this because I bought the truck from the original owner my father-in-law. I am gonna need to touch up some paint issues and am looking to verify color and that it really came that way. The reason I ask is all the research I have done says that the blue motor only came in the suburban in 66 in the 220hp version. So I am wondering if mine was ordered with the bigger motor because it was a camper special C20. My father-in-law bought it off the lot that way it was on special when he bought it. So any help would be appreciated thanks. Heres a pic of color
