I have put several "street" 440,s in different trucks over the years. Is this going to be a work truck, as in towing or hauling or is it going to be a hot rod street truck? Your camshaft selection should be suited to your use. For instance you wouldn't want a big cam in a work truck, you would want a cam meant to provide low end torque. I have a pickup with a 440 and an RV cam in it. Makes lots of low end power, perfect for what I use it for. I also have another pickup with a 440 that has a little more compression and a bigger cam. Really fun to drive!
