Codfish your Dart weighs 3800 lbs with you in it !! Wow thats B-body weight. I know my sons 72 Dart goes about 3550 with his 180 in the car. I wonder why your Dart weighs so much as I figured an all stock Dart A-body with a bigblock would weigh around 3350 to 3450 with out any weight taken out and no driver but yours is even heavier. It runs very good for 3800 lbs. Ron
