Aside from the standard gaskets, sealant, etc., what all is needed (plenum from GM, TB adapter from ????).
Will the fuel rail fit from the Series II?
Anything else I need to know?
Also, I'd need the part #'s for the gaskets and plenum so I can get them from www.gmpartsdirect.com

Thanks again,
Martin

Here is the Post from ClubGP about the L26...

I'll post most of the info on here.

GM Part Number: 89017283
Plenum gasket is included.

As far as matting it to a Series II motor, you will need to buy the Gen5 to L67 adaptor (from ZZP) and more than likely get a TB Gasket from an L67. The "mouth" of the plenum is a tad smaller to the Series II Pluenum since it isn't oval but circle instead. If you want to get a gain out of it, a good choice would be an L67 TB, and port out the "mouth" of the L26 Manifold.
