lightest a-body??

Just some more data to confuse the subject! 63-65 has a small engine compartment. 67-69 has a larger compartment, 70 and up similar to the 67-69 but every year they got heaver with the safety gear. Feather Dusters and Dart Lites, are NOT!
My 67 coupe. 440, 4 speed, blowproof, Dana, Monocoque wheels, subframe connectors, glass hood, glass trunk lid, 8 point cage, lexan windows on the sides, 1 Solar bucket, all the undercoating removed, tubs in the rear..................... weighed 2750 without me in it on a shipping scale. So you can build a lite 67 up car with a reasonable engine compartment or cut the heck out of any car and build it as lite as you can afford. 2000 lbs race cars are not that uncommon, ready to race. IMHO!
