This engine is suited for 2001-2004 Mustangs equipped with the 16 valve Romeo 4.6L engine. Most 1999-(early)2001 cars came with the Windsor version of the 4.6L, which was equivalent in performance to the Romeo but had a several slight differences such as the number of valve cover bolts and the number of flywheel bolts. This beast is a great replacement for a stock car, but can also be used as a performance upgrade with our computer and wiring kit to convert a 1996-1998 GT to the PI valve drive train or to convert 3.8L 6 cylinder models. It boasts around 285 HP from the factory, with an aluminum head design that features overhead camshafts (1 per head). This is a used OEM Mustang engine in good working condition; we will be happy to disclose individual mileage on a per unit basis as we strive to maintain an inventory with under 100,000 miles. All drive trains are subject to our 90 day, unlimited mileage warranty and are available with or without front accessories (additional fees may apply).
