Are you referring to the engine in the u-tube video? If so can you tell us what color of duplicolor that is?
gray engine paint Dupli-Color Ford Gray #DE1611.
I think they call it new ford gray now, not sure if the color changed with the name change. I painted mine a few years ago.
It's not original looking missing the blueish hue some say was original.
But I was happy with the results for my driver.
