aluminum vs steel flywheel for stroker

Thanks Guy's still have some thinking to do about clutch/flywheel choices,Also I do not have any problem emptying a bottle of NOS,I live in somewhat in the sticks here in Wis,--A par time only police man,We built our cars to RUN and have fun,I can never have enough of the rush you get when the nos kicks in and lays rubber ,It is addictive--Steve
