Sounds sweet. Keep in mind trucks are lite in the rear and it sounds like you already have tried to get the power to the ground. Put on some wider tires, softer compound, or maby some "sandbags" in the back. Or you could just put a brick UNDER the loud pedal so it won't go down so far. Ya Right!!!

softer springs in the rear, drag shocks up front to let the front end rise to transfer weight to rear, bigger and softer tires. Or quit poping the clutch at 6k rpm...

Buy a Suburban, lots of weight over the rear tires.

I aswell recommend CalTrac's. If you can't get it to hook on a 28x12 15" Soft Compound tire, then definately get a set of CalTrac's. :yesnod:
EDIT: These tires should do the trick M/T Sportsman's

Click on the information link, More info there

Here is just a piece...

Tremendous benefits can be realized when the CALTRACS traction bar system is installed on a leaf spring suspended automobile. CALTRACS traction bars were developed to achieve specific goals to improve high power traction while staying within hard set NHRA parameters.

Each of the two assemblies needed is comprised of three basic components:

1. Front Pivot

2. Force Transfer Link

3. Rear Mount

The combination of these components changes the pushing point on the car by redirecting the turning action (spring wrap-up) of the rear axle through the Force Transfer Link into the Front Pivot. The Front Pivot Spring Stop Bolt resists this turning motion and also controls the bending of the leaf spring at its thinnest section. The push into the Front Pivot helps the cars weight shift towards the rear of the car because of a new directed angle of force toward the front of the vehicle. (The "Instant Center" moves farther forward). This is where the system emulates a Four link system. The pinion angle is also maintained. (See illustration)
