What's the best engine paint for the red that's on the early slant 6s and 273s?

Noting is correct imo, the international is too bright, ford red is too dark, and the Chrysler industrial isn’t orange enough.

So I personally go with Chrysler Industrial, just because I like that shade the most of the 3.

Here is flash on and flash off of the original 273 commando from my 67 Barracuda. This car was all original 87,000 miles when I got it.
