But what im really wondering about is the sounds the truck makes when shifting under WOT. Going through first gear it doesnt pull too much till it gets to 3000+ then at about 3500 .
Also what are the general comments on running WOT and how it might positively, or negatively affect the drivetrain and engine.

Driving around with a cracked manifold is deffinitely not good. The engine can suck in cooler air, and over time waste a valve. Your fuel mileage is not as good as it could be either.
The design of this motor (4.7 DOHC) dictates higher rpm power than say an old 350 or 454 Chevy push rod motor. Mine is the same way, starts at 3K, runs like a bat out of hell from 3500rpm and up.
I dont use WOT unless im passing, towing or street racing. I agree with the other guy that from a dead stop it puts the most stress on the drive train. In normal day to day driving, I dont need WOT to get around with all the traffic.
