I've got a bad bog off idle when nailing it. Tried it at 1100 and 1500 RPM and no difference. Idles at 1100 in gear. 2 x 750 1407 Edelbrocks. Stock jets and springs, accelerator pump in 3rd (top) hole, 3 inch spacers between carbs and breathers/scoop. Timing is by way of a MSD 6AL-2 programmable. 20 degree retard for start, 36 degrees full in at 1000 RPM. MSD pro-billet locked out.
