my Low dollar 318 hop-up project

Do you happen to know what your car weighs?
If I remember correctly, it was 3160 with the 7.25 rear end, no spare or driver and 1/4 tank of gas. It now has 8.75 rear end, bigger diameter drive shaft, and 15" steel wheels on the back instead of 14's. So I'm thinking we added close to 100 lbs.
