Just for info:
Long strok engine it is when piston diameter smaller then strok.
Shrot strok engine it is when piston diameter bigger then strok.
When piston diameter and strok has the same size-it calls square.
As power output-short strok engines has much more HP and rev much higher, but pick of torque is much later at higher RPM.
The rest of variables (exhaust timing, rod lenght-also known to be conrd ratio, etc) is just moving powerband with limits which are dictated by short/long strok parameters.
BTW, if anybody interested P/L sets for .12 Novarossi based engines for stadium tracks, we have something to offer.
