Carter AFB

I found a old carter afb 9626S in the garage, are these good carbs? is this a mechanical secondary carb? worth trying on the 340?

It's a good carb and it is the one that Edelbrock cloned for their Performer carb series.  The secondaries have an air valve with a counterweight that has to be overcome by air velocity to open.  Very little to no tuning with that part of it and that is certainly a drawback from a high performance standpint.  As for a plug and play carb they are great.  I think it's a 625 cfm so it will work well on your 340 but not allow it's maximum potential.  I don't think you'd be disappointed either just not hitting the max.

I'm currently running a 3310 on my 340 ( 70 motor, stock pistons, 2.02 heads w/t 3 angle valve job, RPM intake, comp 268/454 cam, mopar ignition, headers into 2 1/2 ex) in my 73 charger was wondering if that might be a better carb to try.

Keep the Holley on there.
