My '74 Challenger was the biggest pig in my collection at 3600+



The shipping weight on a base 318 70 Challenger is about 3080lbs, for a base 318 74 its 3225lbs. I cant compare absolute base models, as they didn't make 6cyl Challengers in 74, but the (as close as i could find it) difference is about 145lbs between yours and mine. I helped a friend tear down a 74 so he could part it and there were a few things that i'd never seen before in my 70 and 72's. One thing that i'll never forget was those big massive bulletproof steel plates behind the rear interior panels... i'm assuming to bolster the window cranks (which were always flimsy). Those suckers were heavy. Plus those fat-ass seat belts. It all adds up. Everyone is always looking to take 10-50lbs outta the car to save weight. A true dietician will look for 1lbs where he can find it. The weight-reduction genius will look for a few grams...
