The power output of a typical Limited Modified or sport mod  engine, regardless of the camshaft lift rule, running a  custom built  Holley 4412 is about 30 - 50  horsepower and 20-50 ft/lb of torque below the typical horsepower/torque output numbers we see with our carburetors.  

   With a box stock 4412 the difference could be even greater!  These figures are not trumped up, but are figures that have been verified on a calibrated  SuperFlow 902 dyno.
