This is where it would be nice to find someone who painted the power plants. My '68 GTO's mill was the metallic blue, and I know there wasn't a re-paint. As I recall my convt was not to far off in the #'s from Vikki's by a week or so maybe. But it now has an incorrect block so I don't know the correct color. My cammer-6 (late build) is the metallic blue, and all the '69 cammers I've seen are metallic blue.
