Ford 4.6L DOHC Aluminum Engine Block – Lincoln Aviator Mustang Cobra / Mach1

📦 **Description** **Ford 4.6L DOHC Aluminum Engine Block – WAP Casting – Lincoln Aviator – Standard Bore** Up for sale is a genuine Ford 4.6L DOHC aluminum block pulled from a 2004 Lincoln Aviator. This is the desirable Windsor Aluminum Plant (WAP) casting, one of Ford’s later-production aluminum modular blocks and a proven foundation for high-performance builds. Unlike many “mystery condition” cores, this block has been **personally measured with a Mitutoyo bore gauge** and is confirmed to still be at **factory standard bore (90.2 mm)**. You’re starting with a block that’s not already worn out or over-bored. Factory cross hatching still visible and looking nice. 🔥 **Why This WAP Block is Desirable** - **Stronger bulkheads:** Thicker main webbing than earlier Teksid castings, designed by Ford for added durability. - **Wider main caps & interference-fit cross bolts:** Cross-bolted 6-bolt mains provide rock-solid bottom-end strength. - **Lightweight aluminum:** Shaves pounds off the nose compared to an iron block, making it ideal for performance swaps. - **WAP (Windsor Aluminum Plant) block:** ~85–90 lb bare - **Teksid (Italian casting):** ~88–92 lb bare - **Ford Racing “Aluminator” (late Nemak casting with extra reinforcement):** ~94–95 lb bare - **Iron Cobra block (03–04 Terminator):** ~150–155 lb bare - **Proven in DOHC performance builds:** Commonly used in Cobras, Mach 1s, Marauders, and Aviators. Builders trust WAP blocks for stout street/strip engines in the **800+ HP** range when prepped correctly. 🛠 **Condition** - All cylinders checked with a Mitutoyo bore gauge and found to be standard bore. - Crosshatching still visible in all cylinders. - No cracks, no windowed bulkheads, no broken threads. - **Important:** While this came from a good running 2005 Aviator this is still a used block. As with all used blocks it should be cleaned and inspected by a reputable machine shop before installation. They should **not** be relied upon as a guaranteed source of fitment information. Variations in model years, trims, production dates, and prior repairs can all affect compatibility. **Buyer is solely responsible** for verifying fitment and compatibility **before purchasing**. No returns will be accepted for fitment, compatibility issues, or buyer error. 🚚 **Shipping** I ship with care – not like other sellers who just toss parts in a box with hopes and dreams. This block will be secured and packaged properly to protect it in transit. **Multiple carriers available – prices change drastically between carriers.
