Hypereutectic pistons do offer a number of advantages to Ford.
They are lighter, and run at closer tolerances providing less wear and better oil control. The thermal expansion is very controllable. They're stronger than low-silicon castings anyway...
All fine for a stock/near stock motor.
Definitely not what you need for power adders, though.
and yes, they've been in 5.0's and 4.6's since '93. Ford had a decent set of forgings in there before '93, but they had a tendency to use a higher quantity of oil. All will change with the Cobra in '03. Aren't they Ross? J.E?
