MBHD hav you ever checked out the scientific carb tuning on the
www.bob2000.com/carb.htm website. He uses an o2 with a volt meter for far less $. More like "our" style of getting thingsa done! On another note, has anyone turned their Holly carb sideways as someone mentioned the other day, I'm very curious. Herb 250 heated Clifford with headers 450 Holly with vacuum 2ndaries HEI. Anxious to hear comments.
