That was just a change due to a different method of dyno testing the engines.
The '93 Cobra was rated at 255hp at the crank with a weak cam and 1.7 rockers, and Cobra intake. The gear drive doesn't add power, but can change the powercurve if you've got the cam degreed differently. The B cam is junk, and peak numbers don't tell the whole story. Peak numbers, if I had to guess (not knowing any other parameters of the engine), I would estimate this engine to make about 230-240hp at the wheels, which is about 270-280 at the crank. Low RPM torque suffers with the B cam, and by this I mean that with another cam (ie Stock 5.0 HO cam) it may not make more peak HP and torque but would most definitely be a faster car.
