Engine Color Opinions
For what it's worth, my 67 barracuda 273 is blue (medium blue, whatever it's called. )
I've had hemi orange big blocks, one of my big blocks was painted dark Ford blue, but that one got repainted turquoise. Turquoise is kinda hard paint to find, I think.
If I was putting a 360 (or 408) in my barracuda, I'd probably paint it medium blue, like my 273. Hemi orange is just a little too much like chevy orange to suit me.
But, here's my best answer. It's YOUR CAR! Paint it whatever color YOU want it. Just be aware some purists might not like it.
