Flywheel

HOW do I go about choosing a flywheel? my machinst needs the flywheel ill be running so he can balance everything. , my 4 speed isnt rebuilt yet and, dont have all the parts, z bar, clutch so on and so on, so how do i go about choosing a flywheel??? also im running the scat 9000 series crank, to hook the 833 to the motor correctly all i need is the pilot bushing/bearing right?? is there only one size bushing or do i need something specific, im completly unknowing ???? if that makes sense when it comes to the 4spd. . . . .what all do i need and where can i get it, so far i have


the trans itself( which is abody)
hurst 8inch straight shifter
and shifter rods
and what appears to be the pressure plate
where can i find the right lenth drive shaft to connect with my 8 3/4 rear.??



but more inportantly how do i choose a fly wheel, if u need to know itll be 410 stroker, 8 3/4 rear. 90% street car 10% track car
