I got the ET Street radials 295/55/15 on 8" wide Weld draglites at 16 psi.My '73 cuda weighs 3500lbs.
440 3500stall convertor, 727 tranny, 3.91 gears on stock leaf springs. I found that I need a pretty good burnout to get any decent 60ft times, 1.62 to 1.65 is normal if I leave the line at 1500 rpm.
