DV also said his lobe profile was street car designed lobe, other competitors could be super aggressive and not live long on the street, straining your valve train.
Even through his peak hp numbers were lower than the best cam(-32hp), his average hp numbers were better (-14.6).
I would like to believe that if this competition had degreed every camshaft, optimized timing curves and carb tuning, this whole competition would be a different story. That would take a month of dyno time and $$$$$.
