With your future plans you will grow into those big paceys. They will be costing you some torque now but a cam upgrade will have them agreeing more. Stall and cam. My ute runs a 2500-2800 stall. Look at your dyno graph and find peak torque and launch from just below it and see if the 60ft improves. 2 tenths from a chip is a reasonable gain.
We know that a 14.4 or less is highly likley with a cam and stall change. The 3.9's will be much better when the engine isn't running out of puff after 4500 rpm.
And i'm looking at a couple upgrades before the turbo. When the heads come off for decomp i'll get the inlet ported to match the heads. I'll get the spacer for the manifold (this will yeald a small torque increase for you and help keep the upper cool). I'm also contemplating a 70mm T/B.
