Inside the LS7 Intake.......Pics inside
Inside the LS7 Intake.......Pics inside Well........curiosity got the cat I'm afraid. I just HAD to see the inside of an LS7 intake. I figured this would be helpful to others on this site as well. Note the date on the runner wall.
These manifolds are a slick modular design similar to the FAST intakes. This manifold did not have a part number on it.

Sorry John.......forgot to include the runner length. Measuring down the runner centerline, the runner is 11.0" in length.
Your correct about the born on date. I'm guessing this is a pre production part?

Yes, I thought the runners looked pretty short. How does the runner length compare to the LS1-style manifolds?

What's odd is that recessed "pocket" right behind the TB opening showing on the first pic.

It doesn't appear that these intakes are welded together like the LS6 and truck intakes. This is the only LS7 intake I have in the shop right now but I've heard that the production manifolds have screws on the bottom holding them together like this one. This intake came apart fairly easy. I suspect it was taken apart once before. I'm not sure how the inside of this intake will vary from the rest but I figured since I had the opportunity to share this we all might learn something.

Thank you for posting.
Based on your observations, does this intake look robust enough to be used for forced induction? Since it's not 'welded' I am slightly concerned how tough it will be when 20 psi is thrown at it (having not seen one).
Thanks again!

so whats similar/different between this and the F.A.S.T. intake? and was the F.A.S.T. out before Oct 2003? i wonder if there was a little reverse engineering on somebody's part.

I just have to ask/propose the obvious: Can the L92 manifold be dissected in a similar manner? I.e. is it welded, or perhaps like the LS7, just epoxied together?
If so, the issues of the too-tall-for-an-f-body manifold and long runners optimized for midrange torque are a very simple fix.
And of course in a perfect world, one would just be able to take the center and top sections of the LS7 manifold and slap them onto the L92 bottom section, mated to those gorgeous heads.
Ah, what dreams may come?

it was probably from a prototype run. my buddy works at 3d design services and they sometimes make a handful of a part for pre production projects. they have a ls1 manifold hanging on the wall from 1996.

Some have questioned the epoxy on the vacuum tube. I far as I can see, it's just holding the tube in place. Perhaps it was broken off when the intake was originally separated? I reinspected the inside of the intake and there is absolutely no epoxy anywhere inside. I'll try and get some pics of the intake fitted to the heads. This intake will provide some perspective when bolting up to the standard LS7 or other heads.
