How much does 1971 dodge dart weigh????
My 340 car with a full tank was 3295 lb. It has no heavy options. I would say you are around 3300-3400lb. less if you only run 5 gal of gas. take off 6 pounds or so per gal for that. If this is a drag car you should weigh it and find out you cars weight it is a usfule thing to know as is its weight distribution like rmchrgr said.
Where do you race at now that LACR is closed up?
