ls1mike, peak power at 4500-6000rpm is not usually helpful for towing. While the 6.0L L96 may be not be living to its full potential, the factory setup is quite good for doing work.

Right, but this cam helps lower end just as much as top end. It is a different grind than I used in my Trans Am.

The LS motors make there peak that high but the cam will add through the complete power band, plus not everyone wants a Diesel. I am not saying a gasser is better, but as I recall my BILs 98 Cummins had to live high in it's RPM range towing his old fifth wheel when he pulling grades. I just have no use for a Diesel. Different strokes for different folks.

Not sure how the OP uses his truck but, I only use my truck to tow, so putting a cam in over a weekend is no big deal.
I have the Trans Am or a Supercharged Buick regal that I drive daily.

Mike, I'm an LS fan myself (2000 Trans am/ 2005 Vette). They are great and strong motors but IMO they are for sports cars and grocery getters. Your BIL's 98 Cummins my have had to live in it's higher RPM range but that is still no where near the 6.0's RPM range it has to stay at to compete. My first Cummins was a '99 and I ended up trading it in on an '02 6.0 2500. Didn't take me 6 months to realize that motor was not up to the pulling tasks of my 99 diesel. Don't get me wrong, the 6.0 would spank the Cummins I had unloaded and would have probably pulled the same loads faster but it was a very un-nerving ride with the 6.0. It was always constantly shifting to stay where it needed to be power wise. I now have an '05 diesel and there is no comparison between the two. My truck tows 18,000 and does it at low rpms. It takes a pretty steep and long grade to make it gear down. I can run along at 45-50 on the two lane back roads in OD with very little gear change also. You will never get that out of your LS truck.
