That's an awesome set up you have. I'm not too worried about track times. I'd just like to smoke up the kid who ever dares to rev his honda at me. I really want that awesome glug glug idle.
well lope will come from duration, but just because u have a lopey motor dosn't mean it will start making power where u need it. ok, so duration is the amount of time that a valve is open, with lots of duration u get lope, but the more duration the high in the rpm band the engine will make power (to a point). becasue with more duration u get more overlap, so both valves open at the same time. so with over lap when the piston is moving up to start the comp stroke the intake is still open and u get bleed off @ low rpms.
so if u want just a fun Cruiser u dont want more than 230 @ .050 or maybe less. u can still make alot of power but it will be in a usable range, under 5500 rpm.
