That's the problem, there were NO "340 Four Barrel" emblems at the start of the '70 model year. The A66 "package" didn't exist either at that time. I wonder if there were any 340 4bbl Challenger "road tests" in any magazines?
I have seen flat hood 340 cars and always thought the "R/T hood" was an option (now it appears that may have been an early thing?).
Sort of... Car Life December 1969 has a real early Challenger 340 Sublime, flat hood car on the cover. In that magazine is the "Genghis Grape" 440 six pack 4 speed convertible road test.
Car Life December 1969 article excerpt:
"We had a chance to briefly compare the 440 R/T [sixpack] tested here with a Challenger carrying a 340 engine on 318 suspension. It's on the cover (we like lime-green almost as well as we like metallic grape) but it's not tested because it's not a car you can buy. Dodge built it for another magazine.
We have an interoffice bet on whether the suspension/engine confusion gets noticed there, in case anybody wants to thumb though our rivals on the newsstand
The 318 suspension was softer, as you'd expect, and more comfortable on the highway and over rough roads. Mile understeer showed up on fast turns but the car felt so secure we had to get out and check the thing before we decided it didn't have the optional suspension. The 318 Challenger come with a standard suspension that an enthusiast will like, and that something we don't say very often. The production 340 has and anti roll bar in the back to increase roll stiffness without hurting ride in a straight line. The 440 can't do this, because the big engine need those big spring and more roll resident would make the car skitter off course tail first. Both Challengers we've driven handle well., but we're still looking forward to a real 340."
