I understand the 5.3 responds well to a cam change and a little head work.

I was trying to get some horses out of it by trying to spend as little as possible
but aren't we all. The motor is in my truck and I'm gonna use it for my dd/weekend toy.

Slap a set of AFR or comparable heads, cam, valve springs, maybe some new push rods and lifters and a computer tune and it should be pretty powerful.

I have a 5.3 in my truck. And I am in a similar boat...
Does it have exhaust at all? Is it lifted have big tires or what? What kind of driving do you do on/off road? How much do you want to spend?
Put a full exhaust on it, headers/cat, muffler. Put an intake on it. Get a custom dyno tune, i took my truck to a shop called Pro Dyno, ask for Charles he's a great guy and knows his stuff.
You could also do a cam and stall converter. Depending on the questions above I could reccommend a cam from what I have been told and researched.
You could also do forced induction either a turbo or blower, also based on the questions above.
Also as mentioned above, new heads and a ported throttle body.
The stock drivetrain could handle exhaust, intake, tune; when you get a cam you might need to upgrade depending on the cam. And if you get the FI you would definately need to upgrade the transmission. I know a lot of guys use finish line transmissions, or if you know someone local that could do it (pro dyno probably does).

+1 on the dynatechs though. Thats what I have. They aren't just made just for corvettes. They are made to work well with the LS type engines in trucks and SUV's too.
They are a little pricey but well worth the sound and HP you get out of them
