Chart with engines and paint codes. Can't really add a whole lot to what has been said but I thought the paint chart might help.

That's a good chart, but I found one discrepancy.

I have a 71 Challenger convert 340 and the engine was blue, not hemi orange like the chart says. I think that they "overlapped" a few years....
