The bore is 99.5mm (3.92in) and the stroke is 79mm (3.11in). I am not sure but I think the Cd is .35 for the RS and .32 for the L. The gear ratio's can be found in the links section of this page under Ed Dekker's gear ratio page. The HP and TQ ratings are at the flywheel and all the other spec's Trey at cobbtuning.com would know.
