I have the L31 with a cam and efi and my brother has an 02 truck with a 5.3 and just a cat back and he can out run and out tow me any day.

I can go up hills in my 98 with 1000lbs in the bed locked up in 4th gear at 80mph. Simple freeway overpass hills make any 5.3L I've driven drop a gear unloaded. Sorry but the LS's don't have torque unless you wanna scream, in which case sure they'll do better. Most peeps like a relaxed ride towing long distances though.
