Re: Seriously!! Someone help!!!!
A 3.9 L (238 in³) 12-valve version with 3.8 in (96.5 mm) bore and 3.46 in (87.9 mm) stroke was introduced in 2004. It was installed in a running change on later production 2004 Mustangs before it was replaced by the 4.0 L Cologne OHC engine.
2004 Ford Mustang
2004-2007 Ford Freestar
Ford spec sheets note this engine as 3802 cc (232 in³). The bore and stroke, however, work out to 3857 cc (236 in³). Another strange thing is that this engine, if specs are to be believed, is .010 in underbore compared to the 3.8 and 4.2.
