1)i've got a vibration in my steering wheel.very slight,just started a couple weeks ago.since i got the d/s.i've never felt a d/s vibration so i'm not sure if that's what it is.i doubt it since it's fresh length/weld/bal.seems like a d/s vibration would be more harsh than a slight buzz in the wheel,though.all tires are at 33psi.no handling quirks to suggest worn steering components.the tires are an aggressive tread design with about 10-12000 miles if that.would they be worn enough to give that little vibration.they're a year old now and have had little to no road noise.any ideas?? 2)e-brock carb tuning:500cfm(choking a fresh 350ci?)electric choke.i forget the rich/lean mixture:in=rich/out=lean OR in=lean/out=rich?i also forgot the other q's that i was going to ask. thanks!!
