you do the math.

The 6.0 has 325HP @ 3300RPM, and 570 ft-lbs at 2000RPMs. After 3300 RPM, torque and HP will start to drop.
The efective RPM range on both engines is exactly the same. Except the cummins starts making power and peaks 400 RPM lower - better for towing.
The 5.9 and the 6.0 will both keep going forever at 2900-3000RPM, but I honestly would like to see how long a 6.0 would last going at it at 4100 RPM

I dunno, the cummins has tons of low end torque but the one I drove kinda felt like it lost power once you got up around 2500-2600 rpm (it was a 98 24v) where as my 7.3 felt like it had a little broader power band. i've never driven a 6.0 or 6.4 so i can't comment on them, but from what I read on here they make there power 2k rpm and above.

im not talking about the area betwwen max torgue and max horsepower.
im talking about the begining of usable power thru power tailoff on top.
the 6.0 is deturned stock but is cammed to run up at 4K.
daily drive or tow with the engines and you will see what im talking about.
its double the effective spread and that is why it tows better and has better drivability.

That's what they make transmissions for. To keep your engine rpm's in the powerband. Torque gets it movin', horse power keeps it movin'.
My $.02 has me in a Ford truck for style and durability, a Chevy for the transmission and comfort, and a Dodge for the engine. However, that changes from year to year. Each company will make advances in their trucks that cause me to add, change, or drop a choice. All that said, I drive an '03 Ford.
