This engine is suited for 2005-2010 GT Mustangs equipped with the 3 valve 4.6L engine. This beast is a great replacement for a factory optioned car, but can also be used as a performance upgrade with our computer and wiring kit to convert a 4.0L 6 cylinder car to the GT drive train. It boasts around 315 HP from the factory, with an all-aluminum design that features overhead camshafts and variable camshaft timing. 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).
