6.0 Power Stroke
The 7.3 L (444 CID) Power Stroke was replaced by the 6.0 L (365 CID) midway through the 2003 model year. The 6.0L Power Stroke was used in Ford Super Duty trucks until the 2008 model year but lasted until 2009 in Ford Econoline vans (Model year 2010). The engine has a 3.74 in (95 mm) bore and 4.13 in (105 mm) stroke creating a displacement of 365 cu in (6.0 L) or 5954 cc. It utilizes a variable geometry turbocharger and intercooler, producing 325 hp (242 kW) and 570 lb·ft (773 N·m) with an 18:1 compression ratio, with fuel cutoff at 4200 rpm, but having a redline of 4500 rpm only attainable with aftermarket performance programming.
Some of the 6.0 L Power Stroke engines have proven to be problematic, and speculated to have cost Ford millions of dollars in warranty repairs and buy backs. They led to many recalls and the repurchase of at least 500 trucks, particularly in the first year. However, aftermarket parts exist to address these issues and, with them installed, the 6.0L engine's reliability improves greatly.

Famous quotes containing the words power and/or stroke:
“He admired the terrible recreative power of his memory. It was only with the weakening of this generator whose fecundity diminishes with age that he could hope for his torture to be appeased. But it appeared that the power to make him suffer of one of Odette’s statements seemed exhausted, then one of these statements on which Swann’s spirit had until then not dwelled, an almost new word relayed the others and struck him with new vigor.”
—Marcel Proust (1871–1922)
“This house was designed and constructed with the freedom of stroke of a forester’s axe, without other compass and square than Nature uses.”
—Henry David Thoreau (1817–1862)
