I know Jon favors the small bore and long stroke combined with a relatively short rod. Now that the contest is over maybe they will discuss the combo's specifications. Anybody know the stroke involved?
(4.500 w/4.310 bore would be just a tick over the maximum 510 allowed)

I'm more interested in the actual intake port/runner volumes and actual flow figures from the actual motor- let's face it- until you bolt the heads on, all motors are kind of the same.
The heads are where the power is.
