Nice looking engine. I have used both those paints before and they worked great. If it a driver, race car or hotrod who cares is it's a shade off. Here is a pic of mine it's off a few shades from HEMI orange. O wait it's bright red. It's a street/racecar so lets have some fun and not worry if that bolt is the wrong color or the engine color is a shade off.
That's the same color as on my 71 340. Apparently there were some red ones for a short period of time.
Do you guys use a high heat primer or regular primer on the engine parts?
