wieght of 72 duster

[JoeM29]

i went to mopar nationals the other day, it was the first time i ever had my duster out, due to rain and other complications i was able to get one run, which was a terrible 14.2 @ 98 while going down the track i realized that something was wrong, well to make a long story short my pedal was hitting the carpet only giving me 1/2 throttle, my secondaries were not opening, but i did weight my car and it wieghed 3600 with me in it, i was not ready for the raceing, my trunk was full, with 2 full size spares, all kinds of junk, and some other various stuff, needles to say it is now a lot lighter, but what is the average wieght of a BB duster,
thanks, joe
