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.

Assuming everything else is constant...

Bore will also affect how well the mixture burns, as long as the bore doesn't limit the flame propagation and expansion of the mixture....

Larger bore than stroke will help the engine rev faster, but longer stroke will develope more stroke on the same bore... It's a balance between bore vs stroke... It would be interesting to build identical 340 vs 360 and race them against each other to see how the bore vs stroke affects the output....

My engine professor taught us that the most desireable bore to stroke ratio is 1.2 bore vs stroke...
