It is a bit out of date, but the text of the message goes like this (quoted):
The 6.8L V10 engines in question were installed in vehicles made from 03 March 2003 through 22 April 2003. Ford will replace the engines free until 31 May 2004.
The defective engines have an improper finish on the crankshafts front and rear thrust wall surfaces. This will cause the engine to experience a drive belt misalignment and a belt squeal, low end engine noise due to excessive crank endplay and seized or spun crankshaft bearings.
