002-003 springs are definitly the right springs for a 3100 pound A body ---------We used to run them on a 3600 pound hemi belvedere, with the back of the leaves de clamped, ''used Imperial shocks'', there were a few times when the track was prepped good and our slicks were new, it carried the front wheels to the second gear change. But not often, the track usually sucked !~!
