Jack,
You have a much bigger problem than vibration if you are considering running a 3.58 inch stroke motor at 10,000 rpm, at that speed your "mean piston speed" is 6000 ft/min, most engine designers and builders consider 4500 ft/min the upper limit for performance engines that need to run longer than 10 seconds, i.e. such as Bonneville. I have seen several big block Chevys run pretty reliable at over 5000 ft/min but at the rpm you are looking at regardless of what style crank/rods/pistons you plan to have you are building a hand grenade.
The equation for mean piston speed= 2xrpmxrod length(in inches)/12= mean piston speed in feet/minute.
