What color is the slant 6

That was just a Google grab. I was looking for a "yellow slant six" and that was a cool pic. Not mine, no idea what it came from but the fan belt arrangement may be a 1960 with its generator on the starter side? and the chomed the intake? Pan looks like a car.
The Marine/HO motor came with a 2bbl intake way before the super six setup so that was my reference, and I believe it had a slightly fatter cam, probably more low end for boat RPM's
