I did a quick search, but came up with nothin. Here's the scoop...

My dad just traded our 234k mile 1996 3/4 ton, 2wd, 454 Suburban in for a 2001 1/2 ton 4x4, 5.3 Suburban. It is a better truck in every aspect, except when it comes to pulling our loaded 25' enclosed snowmobile trailer. The LSx motors just don't have the low end that he'd like (he also has an '02 HD 4x4). Does anyone know of a good cam that will put more power a little lower in the rpm range, and also bump up the tq numbers?
Any help is much appreciated!
