What do you want to do with your truck?
Do you need high end racing power?
Do you need low end stump pulling power?
Or do you just need a cool lumpy sound when you pull up to a light?
What other mods do you have to to compliment the desired cam?... a cam alone will not do a great deal... opening a valve earlier or longer wont do that much if the intake can't provide the extra volume of air, or the exhaust let it out the other side.
Do you have a tuner to work with the cam?
+1 on Comp Cams... they have some nice profiles for these trucks... if not going direct, you can get them from Summit.

If you're going to use the H&S1.7's, you'll have to watch the amount lift on the cam.
A cam and 1.7's you will need new valve springs as well.
I'm looking at a CompCams 20-744-9 with H&S1.7's... this puts me at .512"/.512" valve lift.
With 1.6:1 rockers you get .480" valve lift.
Stock is .432", and the max (I believe) is .545".
