      Yup, engines are basically an air pump...the more air/fuel you can pump through them, the more power, and if cubes are limited, then you have no choice but to increase the revs to get more air/fuel through the n/a engine.

      1970 RS/SS350 139K on the clock:
      89 TPI motor w/ 1pc rear seal coupled to a Viper T56 via Mcleod's modular bellhousing w/ hydraulic T/O bearing from the Viper, 12 bolt rear w/ 3.73 gearing, SC&C upper control arms, factory lowers with Delalums, C5 brakes at all four corners, Front Wheels 17x8's with Sumi 255/40/17 and Rear Wheels 17x9's with Sumi 275/40/17.
