150-200 bucks maybe

Straight boosters, manual choke, 2 corner idle.
On a well built 340 they're about 20+ ft lbs of torque down from a 750 dbl pumper above 4500 rpm. They are great for a 318.
 

I think you'd have been better off including the rebuild kit parts separately. As a buyer, I prefer to rebuild it myself than trust the word of a seller of a used carb.

Used carbs are a gamble period...but I dont have any issue with the seller rebuilding it himself. The gaskets are reusable and you can take the 2 bowls off when you change power valves anyways..and inspect it all n set floats. There isnt much to a carburetor... throttle base plate, 2 meter blocks, 2 bowls, a shooter, jets, pv, accelerator pump...check ball or valve..etc.
I get into a carburetor three or four times to tune before I leave it alone.lol
 
Id take that over anything new for the same cfm and should be a good carb when set up correctly. Maybe send it out and get it recoed so it looks prettier.
