I tried a few long-stroke scenarios per my description above. It "thinks" there would be a significant power improvement, but also predicts a bigger cam won't make any additional HP and loses peak torque. Head CSA requirement calcs point to the Victors as being smaller than optimum for best combination of HP and torque, but not by as much as I would have expected.
Obviously, my first question is........ when you modeled the current 3.75 stroke combo, how close is the result to reality?
Then, how much more power is a “significant” improvement?
