I think there's a company called TPIS that modifies the snout and allows for a 90mm opening if that's what you're looking for.

I am very interested on this topic too! I was told that a 90mm Fast TB would go on a un-modded LS-6! Anybody know if this is true? Along with that, what is the best TB for un-modded ls-6 intake?

As far as I know the 90mm Fast TB is a 4 bolt piece, you would need a 3 bolt for the LS6 intake

I'd think a stock ported would be better and cheaper. Whatever size you were to get that's bigger than stock would still be restricted once hitting the ls6 inlet wall. The ported stock would be alot better in my opinion.
