It's neat to see the passenger side valve cover. It has been said that the 1971 340's had the full wire cover on the Passenger side (as seen on the 1970 models). My 340, which I think is complete and original, has the same right side valve cover as yours. 1971 must have been the break year. My 340 Demon's build date was April 1971.
