Couple of things to think about. One what will be the main function of the truck. Street driver with a part time drag or a good drag racer with a part time street function. The drag radial guys have no problem running scary fast on leaf springs. A four link can make a real good rear suspension but the race four links don't make that good of a street setup. Most of the nice riding street four links that work well on a dropped truck may give you problems hooking the truck based on the way they are put in and what the instant center ends up being. Trucks have some issues with working on the drag strip due to the weight split and this problem can be helped with shocks and the ability to be able to adjust the dampening on them. If you can post some info about the amount of power the motor makes, the cam that is in it and what has been done with the trans and converter I may be able to help with getting it down the track. Been drag racing for 35 years and have a dragster now that runs 7.40.
