My truck is a 2005 rcsb with 3500 ptc stall 4:11 gear and locker. LTH intake, built trans. it'll go 8.8 on the motor all night with a 1.89 60ft but it kills off uptop with the stall. I'm getting a 6.0 as soon as i get my truck fixed from the breakin. how much should i be looking to gain going from a stock 5.3 to a cammed/tuned 6.0?

And what is required to do the swap?
