Hey guys,


I have an opportunity to swap my 5.3L out of my 09 Silverado 1500 for a LS2 6.0L. I was looking into rebuilding the 6.0L  engine and upgrading the cam to a stage 2. Anyone have experience with this? As in do I need to change my gear ratio? It has the Z71 tranny 6L80. It is also lifted 6" with 35" tires. I know there are a ton of other questions to be asked and looked at but can anyone give me an idea of a cam that would suit a daily driver to produce more power but not be too much to change out gears or deal with stall converters?

Defining stuff as "stage 1, 2, etc..." doesn't usually tell anyone anything useful.

As far as the actual swap, that depends on what you have stock. Generally speaking, you change axle ratios to compensate for larger tires, not cams and engines. To compensate for that, you want to look into changing the torque converter.
What I generally recommend for engine swap guys is to put the engine in mostly stock, doing only bolt-ons (headers, etc..), make sure your tuning is good and that the setup works with no issues. At that point, see where you want to go from there. I recommend that because these sort of things can nickel and dime you to death, so it's far easier and cheaper to start with a baseline in the vehicle, and to go from there.
