An example is the 440 six pack vs the 426 Hemi... Both engines were rated at 495 ft*lbs of torque and has the same stroke... If bore had more influence on torque why wasn't the 440 putting out more torque???
Cause the Hemi is a built more performance wise. Build both to the same level “hp” and the 440 will make more torque, plus that factory rates not the most reliable source for power ratings.
