The 340 is the biggest POS V8 Chrysler ever made.

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.

My older brother bought a '67 GTO. First day he had it, guy with a 375 hose SS396 Chevelle was giving him a hard time about it. Challenged him, and got spanked. That GTO didn't beat the SS, the driver did. After that, when that SS went to the track, Charlie went along as the driver.
