When the hood goes pop... What makes the jaw drop?

I like period-correct equipment, nothing billet or shiny. My car is a 1967 and I want under the hood to look like a 1967 enthusiast built it to be his daily driver. Clean goes without saying but used is key as well! Of course a hemi is cool but the small block mopar of the day was more common and hard to beat if done correctly.
JMHO--------------DR---------Cheers to all:-)
