I don't have any 340s at the moment. But I don't sell the 340 individually anyway. I sell the 340 driver paired with the 360 "machined" magnum to save members money.
Just go here and you can read about the manifolds I sell:
The price has changed a little so read the whole thread. I do currently have 360 "machined" magnum and machined large hole DAKOTA manifolds available. I'm waiting for a deposit on the last set of 340/360 mag manifolds. If the FABO member doesn't send a deposit then this last set can be yours if you send a deposit.
