Their really not heavy compared to other Mopar body styles. Only compared to an early Chevy Nova or Mustang or something real small like that. I consider my Cuda one of the heaviest A-bodies since it's a fastback and full dress with stereo equip and it's right at 3500 with a full tank of gas (without me in it). Compare that to a Chevelle which weighs at least 200 lbs more. A buddy of mine has a 67 Firebird and it's also 3500 lbs
