Holley 600 questions for 2x4

I never run a choke on anything. Waste of time and they don’t work very well anyway. Mill them off and be done with it.

Are you mounting the carb’s in line or sideways? I prefer sideways. If they are in line you have to take them off to make most any tuning change.

Also, you’ll really need to find a way to figure out if the secondaries even open.
