72 340 choke style

That intake is a 73 intake. The 71-72 340 intake both used the open well with the cup and gasket-a nicer looking choke in my opinion. Then in 73-like your intake used a choke without electric assist, then 74 went with same choke type with the electric assist. All of these chokes are available on Ebay, many as NOS Mopar. Just type in Thermoquad chokes and look for the one that doesn't have a wire on it. There are many that are available.
