Nearly 30 years old and still playing with trucks… Justin Hildebrand may never grow up. But that’s OK. The Bradenton, Florida, shop owner is a regular on the local mega truck scene, partaking in chest-high mud bog slogs, tire-shredding tug o’ wars, and even sled pulls with his sky-high ’04 Super Duty. What’s more—given all the wild engine combinations that often grace these types of trucks—Hildebrand’s F-250 is still equipped with a 6.0L Power Stroke.
Rebuilt for Reliability
Being that his company, JH Diesel & 4x4, is heavily involved in diesel repair and performance, Hildebrand knew that he could make a 6.0L work in the mud—and that it could be reliable. After obtaining a used 6.0L for $800, he tore it down and rebuilt it with a Ford overhaul kit. Other than adding a Stage 2 Colt cam to drive the turbo harder, the short-block is void of upgrades. A few reinforcements were necessary up top. To prevent valve float and reversion, performance valve springs from Hamilton Cams replaced the stockers. To eliminate deflection and any loss of lift at the valves, a set of Manton pushrods got the call. And to keep the resurfaced cylinder heads from lifting, ARP studs fasten them to the block.
