I work with a older friend that back in 1970 went to the dodge dealer to get a 383 or 440 challenger but ended up walking out with a 340 T/A, they were hugely discounting it because nobody wanted the 340 including himself.
But after basically offering to sell it for cost to him he could not pass the deal up. He said it was actually a super fast car and never regretted buying it and of course now regrets ever selling it.
I'd have much preferred a 340 (esp a six pak) over a 383 or 440... but a friend of mine bought a new T/A in '70.. his car would just nip my '70 RR in the 1/4... but a few months later, he traded the 340 sixpak engine to another USAF bud for the Hemi in his '66 Satellite! We spent a while changing out the K member and rebuilding the Hemi before it went into the Challenger TA body..
I often wonder how long my friend (Boyd Cochran) kept that Challenger TA with the Hemi.. he was from the LA area of California, but that has to be a very unique TA..
