Generation IV External Engine - Ls7 intake and nw 92mm tb

Will my nw 92mm throttle body fit on a factory ls7 intake?

Yes...if you are running a cable version, like I do on my Firebird, you need to buy or make (easy to) bracket for your cable. If I remember, I think I had to grind a bit on the RF of the manifold outer to clear the cam that the cable attaches to. The opening of the LS7 was a bit more than 92mm if memory serves me right. Good luck with it.

Yep, opening is actually around 94mm and i opened mine up to 96mm. I have a bracket for you if your interested....

Im not so sure, a lot of people have issues with the throttle body not sealling on the bottom of the throttle body. FAST throttle bodies were designed to work with FAST intakes, NW throttle bodies are designed without the FAST intake in mind.

Thanks for the replies what tb would be the best to run on this intake performance wise it's goin on a 454 ls7. I could always sell the nw tb. I've already ordered this bracket http://sdparts.com/details/scoggin-dickey-parts-center/sd90brkt.

I would run a FAST 92mm TB on that setup.
