    I also believe dynoed HP will exceed advertised figures.

      Believe what you want about dyno figures - and beware that the dyno math correction factors have evolved over time. Other than Popular Hot Rodding magazine's "Engine Masters Challenge" we do not race dynos. The dragstrip is the ultimate dyno, just don't expect Ted Harbit results unless you are Ted Harbit! There are some fairly standard calculations factoring in the weight of the car and the trap speed mph to arrive at a power figure. For those who may wonder: excess wheel spin at launch obviously kills e.t., but usually has almost no effect on mph.

        But why did they offer a less performing engine when the trend was heading toward higher performing engines. Did the superchargers have so much trouble that Studebaker just wanted to eliminate them?
        FWIW, I think a little bit of the rationale was so Avanti owners could have an air conditioned high performance car (factory didn't do a/c on R-3s).
