Get the heads opened up (the valves are smaller than ls1 stock valves) and add a cam. Also, these trucks (silverado's, yukons, tahoes, etc..) respond very well to tunes. Have you added e-fans yet? You can get a set of efans from an 05+ 5.3 truck and they bolt right in. A few people make harnesses for them that work off the stock computer as long as it's tuned for it. The full exhaust will help as well. There's no reason you can't get close to 400 crank hp with a 5.3 and still be very driveable.
