F-bird - Thanks for the questions and pointers. This is a purely street engine, with the truck, a chopped 68 C10, currently getting a C notch and air suspension added to the rear.
I run premium in everything (lawnmowers and ATV included) and this will be the same. Our premium is 92, with one vendor selling 93 (methanol blend).
I was originally planning on picking up a thrashed 350 simply to try a rebuild to see if I remember anything from the 70s, and wound up with a 406 block and some parts, but no heads or intake. A decent street build is the target.

You need to make these decisions and clear distinctions now before you start buying stuff.
