If it does not have enough power, you could always supercharge it! Depending on the gearing of your truck, the 350 should be adequate. I have a 2003 Dodge work truck with a Cummins and a 2000 Chevy work truck with a 454. Believe it or not, the 454 gets better fuel mileage when pulling loads. Empty, the Cummins is better.

Never hold your farts in. They travel up your spine and into your brain...that is where crappy ideas come from.
