My L83 puts out about 480 hp at the crank. With 3.73 gears, 28" tall tire (13" wide) and a 3400 stall, it will fry the tires until you let off the pedal.

I agree with Accelo, knowing the cam specs and tuning the engine are 2 different things. Something isn't set-up right if you cannot smoke the tires in a 2wd truck.
