Rear end ratios are very important in drag racing & hooking-up for launching the car. It also depends on the tires. Street tires (radials) don't need much like 3.23:1 to 3.90:1 Street legal cheater slicks 4.10:1 Drag slicks 4.56:1 All out high hp cars use 4.88:1 Like on my 69', 427 L-88 SS Camaro. Don't forget a posi traction differential & traction bars too.
