There's no such thing as too big of a cam, just too low of a stall! 
I wouldn't say the cam is too big for the engine, but I would say it's on the verge of being too big for a heavy truck, especially one you dd. If it was track only, the cam would probably work with an even higher stall, but for the street it's up to you how much "driveability" you're after.
How does the current engine/stall combination suit your daily driving? If you say "sluggish till 4000 rpm, and only manage 7-10 mpg" then I think you can see the writing on the wall...
I think your combo really favors track use, which will always be at odds with driveability and fuel economy, but it's all up to how much of one you want to sacrifice for the other

Get headers on, get it tuned right, and get some tires that will hook and 12s should not be a problem at all.. That motor needs to breath specially with a cam like that and stock manifolds are killing that thing.
