I like jrp's suggestion of the 216/220 for the 5.3. If you may even want to consider the 212/218 LS6 replacement cam. Either cam likes the juice and will work well with the 3000 stall.
You need headers before the cam. Think headers first.

He owned a tuning shop, that was rwhp, he had over 118 dyno pulls on the truck, and i know that it was a cam air intake and an exhaust cutout. i know that for a fact. it was pretty ridiculous. im looking for a powerband up to 6800,6500 at the bottom 2000,2500.

where are you willing to compromise. i hear " i want, i want, i want..." but somethings got to give with what your giving yourself to work with.

Those cams are way too big,Go with say 210 and 218 on a 114 lda it"ll be better with or without spray in a heavy truck and smaller motor!Talk to Marc,W in the truck section.Or some of the other truck guys.
