i have an 82 camaro which i am currently runnin a 305 in. the 305 is basically standard and i want some more power out of it. what do u guys recommend to beef it up in the horsepower column?

I have a 89 rs with a 305 and the thing that I found that added a good amount of hp, was adding a msd ignition and other msd products, changing the air cleaner to a k n cleaner, and exhaust, also just do a tune up changing all filters.
