Thanks for the clarification Steve! I had read both reports and was a tad bit confused. Easily done...

The new engines to be used by Ford (
at least the V8's ) are the next generation of the International (
formerly Navistar ) Powerstroke diesel, which still uses a cam .Production
of this engine is currently ramping up.
The camless technology will become available sometime between 2005 and
2007. It is currently at the advanced prototype stage. There have been
vehicle trials ( on medium size diesels ) since 1999, but these were
with first-generation systems that were not suitable for production.
Second-generation prototypes are currently being delivered and tested. The
reliability, durability and controls are being worked on, and
production-capable designs are coming together.
Camless valve actuation offers many benefits in terms of fuel economy (
up to 20 % for gasoline, 4 to 8 % for diesel ), emissions (
particularly for diesel ), and driveability. It does not require radical changes
in powertrain and vehicle design, and offers a smooth, incremental path
to the next powertrain generation. Camless engines using systethic (
gas-to-liquid and biomass-based ) fuels appear as the best solution for
the next twenty to thirty years, from both economical and environmental
viewpoints.
