Precision Built To Outlast And Outperform Stock

DFC’s Street Series long block is far more than a basic reman, it’s a full performance-minded rebuild designed with the daily user in mind. Each engine starts with a professionally machined block, bored for oversized pistons, and assembled using all new OEM or equivalent components. That includes new pistons, rings, bearings, seals, and a complete top-end gasket kit to ensure consistent performance and oil-tight operation. The cylinder heads are fully remanufactured with all new seats, valves, guides, and stem seals, plus they’re magnafluxed and resurfaced to verify integrity and sealing. ARP Series 2000 or OptiTorque head studs and ARP connecting rod bolts are included standard, reinforcing the engine’s ability to withstand elevated cylinder pressures and heat cycles. Improved gasket sealing methods are used in known trouble spots to combat common 6.0L leak points. It’s built with the same advanced Rottler machining equipment found in high-end engine shops, ensuring the kind of precision that sets DFC apart from basic reman outfits. This long block is ideal for Powerstroke owners who want a fresh, dependable platform to build on without diving into heavy modifications.
