I'm no expert in paint references, but my guy said paint companies look up "1970 Chevy Truck Ditzler 2163" and cross reference that to their paint that matches.
The 501 definitely has metallic flakes up close, and looks really pretty!
I think you can't go wrong on whatever you paint it, or how you do the trim. A factory swb k10 is a pretty cool truck either way. If you're asking for opinions, I'm with Jocko, factory original baby, hubcaps and all...
