I left around 15 psi with my single 467. 12 pounds in my M&H 12.0/16's worked the best for me.

By the way, I couldn't seem to get much under 13's with my SOVP. Found a used Monster pump and it helped, but I've seen guys run with me on an SOVP

Ditch all but one spring, ditch those factory shocks for something adjustable. The Ranchos work decent if you're on a budget. And you gotta get some kinda traction bar under there, that's killing you right now. Caltracs are great, I have a set and they're awesome on the street, but even a set of home built bars will be better than what you have right now. I have a set of mounts for sell if your interested. Also, I just noticed that you don't have much travel in the rear suspension. From what I can see, you've got maybe an inch before the frame contacts the axle. That's not going to work. You're going to need to cut a bigger C notch and brace the hell out of it, and add some small bump stops as well.
Get your truck on a scale and find out how unbalanced your truck is. Losing weight is ok, but your pulling it out of the back and middle, and none out of the front, where it's heavier. You need to transfer as much weight to the rear tires as possible. Start ditching anything you can out of the front. Toss one of the batteries, move the other to the back. Inner fenders can go too. Pull the front bumper off, don't need that. AC, don't need that, toss that stuff.
You want the front to lift up as soon as you launch and settle back down slowly as you go down the track. Caltrac sells some 90/10 shocks that'll help with that.
Once you shed every ounce you can out of the front and get the suspension done, you'll need to add ballasts to the rear so you can put more weight over the rear axle, and be able to adjust that weight to one side of the bed or the other. You don't have the advantage of a front axle for additional traction, so you need to make those rear tires plant. I plan on running a piece of C channel over the axle and build ballasts out of square tubing filled with concrete, capped off on the ends and handles welded on, as close to 100lbs per ballast as I can get, and two 50lb ballasts as well. I figure about 300-400lbs on hand will be good so I can play with weight and depending on the track I can add or remove weight as needed. And to secure them, I'm going to cut some big chain links and weld them to the channel so I can strap down the ballasts to keep them safe and secure, but look at your rules so you can adhere to any safety rules they may have about ballast mounting.
Hope this helps.
