How much does 1971 dodge dart weigh????

MP chassis book says a '67-'72 A-body will be around 3,100-3,250 depending on how it's equipped. I imagine yours is somewhat lighter but start adding weight back in like big block, frame connectors, roll cage etc you start to negate some of your efforts at saving weight. Necessary items for fast cars yes, but still adds weight. You probably want to find out your weight distribution front to back in a car like yours, probably more relevant than actual weight.
