6.0 FORD STREET SERIES AUTO SPEED OF AIR LONG BLOCK 04 Core Charge Applies plus Core Container Charge (3000) of 500 Crate charge

This DFC Street Series Long Block is a remanufactured engine designed for daily driving, light work, and diesel enthusiasts. It focuses on reliability upgrades over stock, targeting known failure points in the factory 6.0L Powerstroke engine. Key features include improved sealing in common leak zones and heavy-duty internal components. It comes pre-assembled with high-quality ARP or OptiTorque head studs for added durability under pressure, plus ARP rod bolts. Every block is professionally machined using advanced Rottler equipment, then bored to fit oversized pistons for better fitment and performance. The internals are completely new, including pistons, rings, bearings, gaskets, and seals. DFC also includes Total Seal gapless piston rings to help improve combustion and minimize blow-by. The cylinder heads are remanufactured with new valves, guides, seats, and stem seals, and each one is magnafluxed and resurfaced to meet precise tolerances. A full top-end gasket kit is included, and all rockers and pushrods come pre-installed. Backed by a 5-year, 160,000 kilometer warranty.
