Like most Mopars the Plymouth Roadrunner had attitude. I don't know if it was the hard lines or the stance but the Plymouth Roadrunner just gave off the 'I don't care what you think about me, I'm cool' vibe. The Plymouth Roadrunner was a menace on the street and the track. When you saw a Roadrunner cruising up behind you, you knew it meant business. The Roadrunner came with all the good Mopar engines, like the 383, 440 and of course the Hemi. When you matched the iconic Hemi with the Roadrunner you got one of the most potent and legendary muscle cars ever. It just screamed on the track. The sound is unmistakeable and the power could move a house. Drop in a four speed and you pretty much have heaven in a car. The smile on your face would probably be there for the rest of your life. The Plymouth Roadrunner was seriously, one of the greats of the lat '60s. Of course when you're driving your Roadrunner on the street, you could be just happy listening to that Mopar power under the hood. I mean what else sounds like a big block Mopar at 7000 rpm. But some days you'd rather be listening to your favorite songs and that is really hard to do when you have the stock Roadrunner radio.
