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.
yes, I was of age then, and remember them all. The muscle car era is historically significant.
Nine times out of ten back then the better driver won the race. There were many dumb kids with rich parents that bought them their favorite muscle car. I knew a guy that would win in whatever car he drove, and he was a crazy man in his 69 383 Roadrunner.
Unfortunaetly, he went to Vietnam in 70', and did not make it back.
What I like best about my Dart is it thinks it is still 1969! No Computer, no Turbo, no Supercharger, and no worries about someone hacking the GPS or an EMP exploding the electrical system.
Mechanics today can't troubleshoot a newer car without a computer. I tell them all the time: back then your brain was the computer, you had to listen to the exhaust system and engine, smell the exhaust ,and calculate everything in your head, using only a timing light and vacuum gauge!
Ah, the good ole days!

Whenever I open the garage up, Purple Haze(jimi Hendrix for the youngens here) starts playing on the radio! I went in the military in the summer of 70', and $100 bucks a month didn't go far to own anything newer than a 66 Polara. I was lucky to afford that, with a $40 dollars per month car Payment.
