318 - 340 Same Torque??

It may be advantageous for manufacturers to advertise more power for their base engines, 225 and 318 for instance. But advantageous to advertise their performance engines lower to help out the racers, Hemi,440, 340.

Note that a 340 is listed as 275 hp at 5000. Maybe true, but how much at 5500? 295? Same for the 426 Hemi, 425 at 5000.
Note the heading says horsepower, not MAX HP.
