Can anyone come up with a picture of a 3800 III N/A motor with the dust cover off?? It would be nice to see a picture of the new series III aluminum upper intake manifold.
You would think this is some kind of government secret the way the Dealership acts.

Hell, I haven't even SEEN the Series III personally yet. Something I need to go do. You wondering if it'll bolt up?

If it bolts up that would be so sweet for L36 owners

As long as the heat disipated doesn't accelerate the errosion of the lower or upper intake gaskets!!! But it would so nice!!

I seriously doubt that would be an issue. The 87-91 and first half of 92 had aluminum intakes with no deterioration problems with regards to gaskets.

Good point...

Looked at a 2004 Grand Prix on the showroom floor, with the cover still in place, from the PCV valve end it looks like the series II manifold except aluminum. The dealer had a 2004 Regal next to the Grand Prix and it made it easy to compare the two motors. The injectors and the throttle body look different but that is all I could see with the cover still covering the manifold.
If GM did not change the bolt spacing on the upper manifold there may be a chance to adapt it to a 3800 II (L36).
I f anyone has a 3800 III motor or has a friend with one please take a picture and post it.
