Correct Engine Color

I have a '68 340 Dart. I told the machine shop to paint it Hemi Orange. I told the paint shop I needed a rattle can of Hemi Orange. They are not close to the same. I can't tell which one looks more "Cheby", but the machine shop came closer to the color that the engine was when I bought the car many moons ago. Which looks more like "Hemi Orange" to you? What is the correct color for the '68 340?
