Looks like you're going to have he same build as me with a slightly larger cam and stall. I'm a 2011 CCSB with a 4/6 drop, 22s, 212/218 cam, ported heads, and 3000-3200 stall. I just ordered a coil over conversion for the front of mine as I wasn't happy with the ride of the drop struts up front. I'm doing towing bags in back and a rear sway bar as well for some better street manners. I'll probably do caltracs eventually too lol. My truck is 4wd and put down 342hp/348tq rolling on 22s. Make sure you upgrade the driveshaft as they're known to let go at around 100mpg

 

Oh and I'm going 4.11 gears because I like the look of 285/45/22s and I think it'll be a better all around gear since the tire is 32" tall

 

looks good man. I would say the cam is a bit large for the 5.3l but that's me. I am running 3.73's w/6l80e and its perfect. 4.10 would be a bit quicker but highway speeds you would be almost to 2500 rpm's.
