New Guy to MOPAR world

hi team. well, ill start right off with a bunch of questions on a restore im getting ready to start. forgive me if some of the questions sound novis, im really good at things, once i know what its suppose to be or look like... here goes:

1972 dart swinger. has factory hood scoops (2). do they have a functional air cleaner for ram air or cold air intake
are they painted body color, black, simi gls, flat, or that texture like on a road runner hood. the hood is black over to the hood pins, how far from the finder does the black start. with the hood scoops, do i still use insulation?

how much difference in appearance is a 318 and 340 other than color.

i have the build sheet, and will get you guys to decode for me when i pick it up next week. it is a high option car, auto, air, ps,ps, disc brakes, delux interior, etc. bench seat without arm rest. ok enough for now, I will be a frequent viewer on way to senior tech! by the time im done. :-D:toothy10:
