I dont know if I understand what you mean.  Th longer the stroke, the
longer the lever the piston has on the flywhel, giving more toque.  But
the piston speed is finite, and with a longer stroke, the piston speed
will be higher for the same RPM of a smaller stroke motor...Thats one of
the reasons smaller motors are considered better for hi rpm.

I think the thing of it is is cost vs return(been talkin alot aobut that
latley), and foralot less than the cost of doing a stroker bottemend, you
can put on a turbo that will make the car perform jus as good.
