bore vs stroke

But the funny thing is, the engine masters video refutes that. The short stroke BBM made more torque over a broader span than the long stroke Chevy.
I was surprised.


Yes but your not accounting a smaller pistons is gonna have less force against the longer stroke than a larger piston against shorter stroke.
Stroke is only one part of the equation.

Eg.. A weak man with a longer pry bar vs a strong man with a shorter pry bar could be made to be even depending on the lengths.


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???
