I watched the episode. Torque and HP increased throughout the RPM range tested over the 240's. Pretty good increase.
Now if they would stick a set of ported 440-1s on it to see if there is any difference. B1 or Predators would not be a fair test because of piston change. 440-1 would be a lifter and rocker change but that is something that can happen with the engine still in the car.
