That cam might be a little on the big side if you are planing on driving the pickup on long trips. Download this free desktop dyno to help you choose a cam:
I HIGHLY recomend a roller cam though. I have been through 2 big blocks in my pickup due to the hydrolic flat tappet cam going flat. Total miles between both of them is under 7000. Both motors were built by pros. Oil companies quit putting zinc in oil, without it flat tappet cams don't last as long.
