Is/was there ever a 340 Magnum

As previously mentioned Challenger said 340 Four Barrel...

I don't recall seeing 340 Magnum on any 70/71/72 Mopars... 73 Charger Rally is the first & only car I recall seeing that badge on... And they were pretty big, like the 440-Sixpack and 426-Hemi badges.... the 440-Magnum/383-Magnum & 340 Four Barrel badges were all small letters..
My neighbor had one and it was incredibly nice. Dark Blue with the black hood treatment. It was really sharp. The Callouts were definitely 340 magnum.
