The 340 is the biggest POS V8 Chrysler ever made.

My take on "modern " is, that the cars are too expensive, especially performance models, and that there isn't as much to choose from. back in the day, and lets stay with A body Mopar, Mustang etc. these cars had an economy "Base" model, and a performance optioned model for a few $$$ more. You could pick options, and pretty much have a 340 Swinger with nothing in it, no radio, no A/C etc. and you could take the car to the track. Now, there isn't much in choices, if you buy a Shelby Cobra, or Challenger Hellcat, you had better be making 6 figures to pull off the car payments every month. I don't suspect it was that difficult to make payments on a $3200 Dart Swinger 340 back in 1970 making $ 5-7 bucks an hour, I am not sure though wasn't a working adult then, maybe some older folk may chime in.
