$1000 to 1500 would be realistic.


When you say exhaust, have you done headers-back or cat-back?

Once you've done those, then cam, then heads is the typical power path on these. 30-50 HP is a more typical number that you could expect with a cam on top of those other mods, without moving the powerband up too much. This ought to have a 5.3 around 375-400hp, depending on which one you started with.

I have never seen anyone called out like this on GL4x4. Ever. This was even better than the guy that smokes pot with his kids.

Awesome thread. Great for a good laugh. I don't think I've ever seen anybody puff up his chest and spout off, then been humbled so bad. As an added bonus, I learned a lot.
