I know that the new 3.5/3.7 duratec (may be true for 3.0) has s-vt, which means "timing", and our 2.5 doesn't have.

Here, let me try again since the first time didn't take.

NO.

There is no Variable Valve ANYTHING on the stock Duratec in a cougar.

Some Duratec engines do have VVT, but none that I know of can change the Valve Lift.

I think the Hydraulic valve adjusters you're thinking of is to adjust the Valve Lash, Not change the valve lift.

...And we're done here. Before the flame war starts. Question answered- None of the Duratecs that came with or fit into the Cougars (without stupid amounts of re-wiring) use any type of valve adjustment.

The HLAs control lash- Just like their name implies.
