1971 Duser 340 H code 4 spd

The biggest difference would be with the 10.25cr motor and the 2.02 heads on the 71's, they were quicker, then a BIG next would be the ralley dash IMO much nicer than the 72's, Then you have smaller differences like the cone center caps on the ralleys, the Black wrinkle finish "open" air cleaner, the air metered 71 T-quad patterned after the competition series t-quads, (More than a few experts and class racers agree this is the best performance Quad) the later t-quads were a better daily driver carb. Next the pre April 71 340's were Street hemi orange and not blue, Marker lites were flush with the body and don't stick out like later years, so all in all the 71's usually bring about 20% more in what i have noticed in the last 10 years or so that i have been watching these.
