LS6 vs TBSS Intake
Fitment shouldn't be an issue. I don't know how much better the TBSS intake is over the LS6 intake. Do you already have the TBSS intake? I haven't looked, but I would expect they are damn hard to find.
Hotrod compared several LS intakes dyno testing. Interesting read.

That is an excellent response, Black Bird. I especially appreciate the link to the source of information, as well as the disclaimer you added at the end about the results being on an engine dyno and specific to the engine used for the test.

Happy to share that article. I think it's a good read.
Eventually, I want to do another LS1 or LS2 swap for my other 3rd gen Camaro and dyno the LS6 vs TBSS for a typical heads & cam set up. I wish Dorman would get their LS2 90mm intake out for us to test too!

Yes its better, it has the advantage of being much bigger. Remember it's designed to work with truck accs and no windshield overhang. If you can overcome that youre golden.
The TBSS intake is several inches taller than an LS6. It's not going to fit in an f-body without major cowl modification.

For reference, the TBSS Intake is about the size of a whipple supercharger on top of the engine.

The TBSS & LSXRT both will fit in a 3rd Gen fbody Camaro. I'm not sure if they will in the 3rd gen Firebird with its sharper raking hood profile.
My 91 RS had the LSXRT for a while.
If trying to get a TBSS into a 4th Gen fbody, how much space would lower profile engine mounts to provide?
