From GM, the truck intake on the LQ9 supports 350hp on a 6.0, the LS1 supports 350hp on a 5.7, the LS6 intake supports 400hp on a 5.7.
Your 5.3 is under 300hp. Unless you change cam & springs or heads, and exhaust, and really spin the engine fast, none will make much difference on your 5.3.
I only went to an LS1 for the low profile to fit under my hood.

Well If you look at the real Data. No, Its not worth the time and effort. You would be better suited to spend the money on a cam swap.
In stock forum Just swaping between the 2 intakes won't net much if at all.

If I remember correctly You could gain a few HP at the very top end, but what you gain in hp you lose in torque. Also you have to consider How much time you plan on reving the motor to get that small peak of additional HP???
