I just purchased my 2004 Lariat Screw and was wondering what the differences were between the 5.4 liter I had in my 2000 and the 5.4 in the 04's besides 3 valves per cylinder. It doesn't have variable valve timing does it?

 

Actually is there a site that tells us about all the changes in the 5.4 from 1996 - present?

 

Yes, the 2004 5.4 does use Variable Valve Technology.

The circuit is fed via oil pressure.

I've always been a big fan of the technology from my experiences with Hondas (cars and motorcycles).

Thats how Honda manages to get 240 hp out of 2000 cc in the S2000.

Here are some tech specs for you to peruse:
