My car is a 1985 T/A. It has a 305 4bbl in it, and the guy I bought it off said that it was rebuilt, couple of years ago I didn't know **** about **** with cars and I never bothered to ask him what kind of parts it was rebuilt with, wether it be performance or not. So assuming it's a pretty much stock engine, possible rebuilt a little better, I know there is dynomax headers and exhaust system on it, what would be my best options in the way of power adders.

Nitrous,
it's cheap and requires less skill to put on than a supercharger or turbo.

Would there be any options for a procharger type setup for that or would you have to use roots style supercharger for 4bbl?

you can make a blowthrough(procharger style) carb. i've posted the link a couple of times, just do a little search.

Best bet is to throw a nitrous kit on it. Supercharging or turbocharging is out of your league.

lol I understand this, but a couple of my buddie at the machine shop would be able to help me out there, I just want to know if a centrifugal supercharger would be possible without the same carb tuning involved with turbo.

Same deal more or less tuning...
