Engine paint decision and questions

Rustoleum Regal Red is pretty close to the original color. I've painted several engines with Rustoleum with good results. The stuff dries slow, and stays a little tender, but once the engine is running it bakes on real nice.

Is Regal red dark? I wanted something brighter possibly. Maybe I should do race hemi orange instead? Or would that effect the value of the car? Or does that seem odd that the engine in a 65’ Barracuda should be red?
