6.4L Powerstroke Specs

6.4L Power Stroke Horsepower & Torque Curve

6.4L Power Stroke Engine Serial Number Location

The serial number for a 6.4L Power Stroke engine is located on a half moon shaped section of the engine block on the driver's side, rear of the engine. A sticker that is applied during production will need to be removed in order to see the serial number. The first two digits will read "6.4", followed by a four digit manufacturing designator (HU2Y for engines built in Huntsville, AL and HU2U for engines built in Indianapolis, IN), and the final 7 digits are the sequential build number. The same information is also available on the front of the engine, on a sticker mounted on the EGR cooler. Here you will find the plant at which the engine was produced as well as the build number (build number is the last 7 digits of the number posted just above the lower barcode).

Additional 6.4L Power Stroke Info

• The 6.4L Power Stroke is based on International's Maxxforce 7. The engine's are essentially the same, save for a few differences such as output and maximum engine speed. The "Power Stroke" name is unique to the engine when used in Ford pickups.
• The 6.4L Power Stroke is the first of its breed to feature twin turbochargers, giving the 6.4L quick throttle response & plenty of airflow at higher engine speeds.
• The 6.4L Power Stroke was the cleanest and most powerful Power Stroke produced at its introduction, featuring advanced emissions controls and peaking at 350 hp & 650 lb-ft of torque.
• International suggests that the 6.4L is the most durable engine they have supplied to Ford.
• Due to the emissions controls, specifically the active regeneration mode (when the engine speed is increased & fuel is introduced into the exhaust system to burn off excess soot in the particulate filter), the 6.4L suffers from poor fuel mileage when compared to previous engines.
• The 6.4L requires the use of ULSD only. High sulfur diesel fuels (greater than 500 ppm sulfur) can damage the EGR & diesel particulate filter by causing corrosion.
• In an effort to eliminate head gaskets failures (which were relatively common on the 6.0L), the 6.4L features larger M16 head bolts, and there are 4 head bolts per cylinder.

6.4L Power Stroke Flaming Exhaust

Ford safety recall 07S49 applies to trucks built before 3/9/2007, and addresses concerns of flaming exhaust due to excessive exhaust heat during regeneration on the 6.4L Power Stroke. The recall updates engine calibration and solves this issue as well as many other DPF/active regeneration related concerns by altering the regeneration schedule. Very few trucks were affected, although a video made viral on the internet that featured a 6.4L with flames shooting out of the exhaust made the issue seem common. Many suspect the owner of the truck in the video altered the truck to create the flames. Owners should not be concerned, the recall was small and all trucks have the updated calibration, which permanently prevents the problem.

While the 6.4L Power Stroke production run only lasted a few years, International's medium duty engine proved to be a pace setter in the light duty truck market. International's decision to utilize twin turbochargers and finally turn to common rail injection technology helped the 6.4L Power Stroke stay competitive with GM's & Dodge's offerings. The greatest complaint that the 6.4L received was fuel economy. The addition of the diesel particulate filter & active regeneration system hindered the city fuel mileage (stop & go) of these trucks, though an unloaded truck could still provide acceptable mileage on the highway.
