we are running 17psi now
he was running 12psi and using nitrous out of the hole to get that big truck moving with the long first gear.
on 12psi and a 80 shot it went 11.54
it went 11.9 on 12lbs alone the nitrous launch just cuts a better 60ft
we are gunna run it again soon, this friday probably with 28 inch slicks and 17psi only and see how it launches, if the 60ft is weak still we will give her a little juice again haha

08s are easier to put 4l80's in,
you should swap on the stock manifolds if you go turbo and sell the headers.
the 3.73s would be a little agressive but should work out fine
