No, you do not have to change the secondary plate in order to change mixture. You can drill the orifices. If you move to tuning these carbs, a set of wire drills will save you a lot of money anyway. Master, again and still

Depends on how old your 3310 carb is. For many years the 3310 had a metering block in the secondaries. Not sure why or when they switched to a plate. The 3310 and the 3310-1 had metering blocks and where rated as 780 cfm. The 3310-2 and newer have metering plates and are rated at 750 cfm. In theory, there is no difference between theory and practice. In practice, there is.

It is jetted really lean so it backfires when cold or when I throttle up suddenly. My 670 Truck avenger was really lean also. I opened up the idle restrictors to about 0.032" (I think they were about 0.028 or smaller.) That made a big difference in off-idle response because it richens up the transition circuit before the main circuit kicks in.
