Smiggs, i guess i was talking about durability over performance. I mean, in 20 years, will people look back and say "that was a good engine".
I heard that the 5.4 does have piston slap due to the longer stroke.

As far as the dohc thing, didn't they use them in the lincoln avaitor and similar models?
It seems like the trucks don't get the good stuff. Almost as if they don't have to try too hard. Look at the e series vans. They didn't even get the 3 valve heads that the f150 has. Neither of those got the 4 valve heads.

I think the modular moniker is more of a way to differentiate it from the windsor and other series.
