Per the Moparts archives, 67-71 A engined A bodies weigh 3000- 3200 lbs. Do you feel that weight saves that much more gas than aerodynamics?
Those numbers are out of the MP books. They are all light on reality.
My 68 Cuda coupe 340 auto 11.75 disk conversion aluminum intake non A/C car steel rims 1/2 tank gas lighter weight modern bucket seats aluminum master after market steering wheel (pick up a rallye steering wheel sometime!)
All that was 3340 on a cert. grain elevator scale.
