So I received a ported intake manifold today, and am expecting mixed results when it gets installed in late October. I've heard anecdotal reports from other folks who drive cars with the 3800 Series II engine in my LeSabre that they've picked up 1 mpg both city and highway from just this mod. I'll see.

In general, I heard porting things did increase power, and so increases fuel efficiency since the engine isn't working as hard to get air in. I do a lot of highway driving, and will be putting a lot of highway miles on my car later this fall. Therefore closed-throttle operation is not as important for me as highway efficiency, and my fingers are crossed this helps boost part-throttle efficiency.
