Goldmember, you better check your scales...I have never heard of a car that light without extreme lightening. My 72 dart weighs 3500 with me, aluminum headed small block, full exhaust, and a 75 pound moly roll bar. My buddies 68 dart is lightened a bunch with fiberglass hood, bumpers, and brackets, aluminum interior, one race bucket seat, lexan, aluminum headed 383, and it weighs 3020 with driver. I am sure he could get it under 2900 with more fiberglass, and a moly cage in place of the mild steel one.

I know a belvedere is probably a little lighter than a sport fury, but my big block four speed 65 weighed 4200 with me in it.
