In the May '10 issue we showed you how to put a 7.3L Power Stroke together from the ground up and explained many of the tips and tricks involved in rebuilding one (including a forged connecting rod upgrade). This time, we're back to show you how to resurrect the 7.3L's successor, the 6.0L Power Stroke, using more genuine (and affordable) Ford parts.

The U.S. Navy, in collaboration with the aerospace company Aerojet and the energy company Biodiesel Industries, may have developed the ultimate weapon. This device might not be as glamorous as a fighter jet or as intimidating as an aircraft carrier, but it is just as important-perhaps even more so. Throughout history, military campaigns have always been reliant on their supply lines. Today, delivering fuel to U.S. fighting forces around the world is one of our biggest logistical burdens, in terms of financial cost and the number of lives lost. Without fuel, our military's planes, ground vehicles, ships, and generators would be useless.

Back in February 2009, we rescued this '87 Ford F-250 from a one-way trip to the junkyard. We got its 6.9L IDI diesel engine, ZF five-speed transmission, and twin I-beam, two-wheel-drive suspension resurrected with the items listed on the next page. This month we've modified the ATS-turbocharged engine with a Snow Performance Diesel Stage 3 MPG-MAX water-methanol injection system.

Diesel engines are at their best when the conditions they have to perform in are at their worst. They thrive on hard work, heavy loads, and continuous use-so it's no surprise that diesels are the powerplant of choice in the trucking, mining, and marine worlds.
