5.3 Performance,and 4l60e Performance

[CTurner03]

Looking to get some info on what is out there to do to the 5.3? besides headers,cold air,throttle body,and programmer, and transmission, im kinda wondering if there is different aftermarket torques out there, and different internals, hope someone can give me a heads up on all this. and giving me some good combos and ideas

Cam swap is pretty popular

You won't gain a thing from shorty headers, the throttle body mods/add-ons and minimal gain (a power shift really, to higher RPMs where you'll never use it) from a CAI. Having a real tuner like Black Bear (not the pre-packaged stuff) is the best place to start before doing hard parts like a cam swap.
