I'll take a stab, although you didn't note the induction system or compression, or exhaust...?... all of which plays into the equation.
Anywho - If it's a 4X4 haul'n 2 tons, you need to select a cam with minimal overlap, like 20 to 30 degrees. That cam looks potent, if the overlap is in that range.
Just my 1 cents.
