RA is not RA without the Ram Air induction. I printed the email from Jim Mattison several months ago, and he is generally accepted as having a fair amount of knowledge about Pontiacs. You are still in denial, and that's fine, but don't fool others into thinking that 400 H.O.s are really Ram Air IIIs when the two are separate submodels.
348 = H.O. 348 + 611 = Ram Air
RPO is the ONLY factor that affects the build of the car.
