Default LS3 Intake recommendations

I am in the middle of a turbo LS3 build.
I like the low-rise efi Holley intake, but it looks like it is for the LS.
Other than FAST, any recommendations on an intake?
Stock or maybe LS7?

I do have the stock heads. I'll call Holley. The one listed on their site is for the LS1.
A few people said to get a sheet metal/aluminum one made. That intake is not in the budget.

The stock LS3 intake manifold should flow more than enough air to suit your needs plus it's a lot cheaper. LS7 intake won't work.

Sure it will, the stock LS3 heads and intake flow quite a bit of air even in stock form.

Stay with the stock intake. It will work well with force induction.

If I could rewind I would've kept my ported LS3 intake. I don't see the need to spend double. I even think the stock is stronger.

To RyanSws6, funny you say that bc my buddy has a 408 in his ta with ls3 heads and a fast 102. Yesterday I went with him to tick performance to test hp difference between the fast and stock ls3 intakes, and I think the diff was amazing. The ls3 made 13 more peak hp and 8 trq at peak, but that's not what amazed me, it was that the ls3 made 25 hp and 34 trq at 3700 rpm. The 102 fast had a 102 throttle body and the ls3 intake had a 92mm TB. I know this was on a N/A motor and it might be different with forced induction.

Holley makes a rectangle port intake, but nothing is wrong with the stock LS3 intake. If its being used at over 500 HP N/A, it'll flow enough for a boosted setup at twice that.
