So I'm looking to get into a Plymouth Satellite or Belvedere that will most likely have a stock 318 in it (hoping for a 383.) My question is, What kind of horsepower am I looking to get out of it? And what would be the easiest way to get some big horses and torque from it with out putting a huge sum of money into it?

I know cams, carbs, intakes and headers are the big ones, but what else? I want a lot of get-up-and-go. what would you all start with?

I'm new to Mopar.
