There wasn't any one particular part of this for me to highlight, but I'm really glad you covered these things. My opinion may be more biased towards "appearance" and utility which is subjective vs "overall weight, weight distribution, and wheelbase" which is objective. I definitely prefer the Roadrunner, but before
I took a serious "perspective buyer's" drive of a ?71 Demon/Duster 440 auto. It was loud in a beautifully healthy manner and it certainly had the performance to back up the menacing vibes...POWER-TO-WEIGHT in spades!! I mean WOW! a big block A-body defines that combo!
It looked great, paint was that "real" RED (no orange in it) with black stripes...BAD ASSED
BUT
The factory shoulder strap grabbed me right across my neck, literally! So unless Chrysler had some diabolical secret scheme in league with "The WEF and The Illuminati" to reduce the population of big, tall men, that is just how my 6'3" 270# frame fits in an A-body and that made me look at or see easily all the other ways A-bodies are too small for me as a CRUISER that I race occasionally. If I wanted a track car, I may not look at anything but an A-body!
That takes me to my B-body, and a Roadrunner at that. Still a reasonable size car, not something that you need a crew to dock in a parking spot, and I think the 68-70 Roadrunner is lighter than the 71-74 and my 71 Charger R/T certainly felt way heavier. The interior space is comfortable, especially since I switched out the vinyl covered behemoth of a Bench Seat for a couple of SCAT ProCar bucket seats in Yellow and Black at that, and added a matching center console. TOTALLY changed the vibe inside and made it "racy-er" and still weighing less than if I hadn't done anything.
I may be wrong about this but I believe the longer wheelbase of a B-body makes it harder to get sideways under power, and easier to recover from a slip?
Last note on this and I'll probably just read the rest of this thread in peaceful silent observance:
I can assure you that even if my bold colored metal "Voice of the Roadrunner" horn weighed a ridiculous TEN POUNDS there are no fractions of a second or +MPH that I would trade it for, because it is great to give a "Beep-Beep" to the people who line up, gather, and park all along Beach Highway for Cruisin the Coast and specifically ask to hear it, and that saves me some tread on my drag radials because "smokin' em UP!" is the other popular request!
Great thread, I'm out, and apologies for hijacking.
