360 stroker how much HP is picked up if everything else stays the same?

Bakerlite,
Post #86. I will spell it out for you. Think of a disc brake system. The force of the pad creates friction against the disc. If you use a larger piston, you create more force & the pad pushes harder [ more friction ] against the disc.

In the cyl bore of the engine. Large bore, small stroke. The side thrust on the piston against the bore. If you increase the area of the piston that contacts the bore, it is like using a larger piston in the brake example.
