not as heavy as ya think. weigh that 70 challenger say with a small block and compare it to say a 73 small block duster. i think you would be surprised.
I looked and couldn't find a comparison between the two....The one I had had a 383 in it so I could only go off of it being a big block car....Do you know the difference in weight? I would like to know....With the new Chally's with all the safety features and "creature comforts" then I can see why it's heavy, actually any car as a matter of fact......I only see cars being "light" when all those things are removed BUT then you get into "race car" status and sells of said vehicles would go down greatly or not at all.....
