mild? screw that...3800 all the way!

Rather mild cam but good choice seeing as you've got no overdrive and.. well... your driving isn't exactly "environmentally friendly."
You're really going to need to crank up the fuel pressure. I'd guess at least 20psi but I'd go more like 25. Those GM injectors can handle 50psi so I think 25 is a good number to shoot for.

A 3800 stall would kill the truck....all it's power is low end torque, not nearly as much up top.

I'd say the truck will start running a bit deeper into the 13's now
