Horsepower estimate?

Interesting you can use the same basic combo on the Desktop Dyno but switch to a Chevy 350 and the HP stays the same but the Chevy has less torque by 10 lb/ft. Must be the rod ratio.

It's the stroke. 350=3.48" stroke. 360=3.58" stroke. That's .100". That's a great example of stroke adding torque.
