Is this a race only truck. If it is a race only truck. I suggest adjustable race shocks 70/30 on the front, 50/50 on the back. On our race car in the avatar it has those shocks, plus air bags, and a sway bar.
We have it set up like a poor mans four link. That is only a 267 with a 2 barrell causing all that lift. so it works!
But air bags or ballast could help you with the truck, trucks have terrible weight transfer
