Personally, I do not like the factory intakes. I do not like any of the plastic intakes or aluminum intakes that look like the factory intakes. All of them hurt the heads air flow. I personaly would not waist my money or time on any of those intakes. There are intakes out there that will help the heads, but the LS1, the LS6, the Fast intakes, or any of the other stock copys, will not do anything but waist your money.
Stick with a ls6 or a fast. I cant see any reason for you to go to a bbk when it is not going to flow any better but yet is heavier and will hold more heat then a ls6.
If you plan to make a lot of hp later, go fast once and be done. Port it down the road when you make more power.

I say go LS6 for now.. Nice proven piece that doesn't heat soak... then after you get your cam and you're looking to go for a nice set of heads and maybe a bigger cam (cuz you want to build a power monster) I'd go with the FAST 90 and a nice TB...
I may be selling my LS6 here in a couple months/weeks.. When are you looking to get one?

Well I have the BBK and its a nice piece...
The reason I went with the BBK is because I was planing on running a little shot of nitrous this next summer. I didnt want a little nitrous fire/backfire to blow a hole threw or melt a new $300+ LS6 Intake.
Cons: Heat soak & weight. The BBK Intake is just like ur heads and block, it gets hot and stays hot for a long time. And it is alot heavier than a Ls1/6/LSX intake.
I guess what sold me was reading a book by Richard Holdener called "Dyno-Proven GM LS1 Thru LS7 Performance Parts."
They tested a bunch of intakes on the same motor. Showed the dyno charts for each intake.
Base line with LS1 462hp 440ft-lbs
LS6 474hp 449ft-lbs
BBK 489hp 450ft-lbs
LSX 482hp 451ft-lbs
The dyno charts showed the BBK gained hp&ft-lbs threw out the rev range. The Fast LSX lost a little hp under 3500rpm & lost a good amount of ft-lbs under 3600rpm.
Thats just on one engine, but it sold me...
Just my 2 cents, im not hatein on anybodys setup...

There is nothing wrong with an ls6 intake. great performers untill you make over say 420 at the wheels then step up to a fast 90. You will kill your power with a carb intake with the fuel injection on stock cubes and in most cases with big cubes unless you get a special cut cam for the short runner intake.
Stick with a ls6 or a fast. I cant see any reason for you to go to a bbk when it is not going to flow any better but yet is heavier and will hold more heat then a ls6.
If you plan to make a lot of hp later, go fast once and be done. Port it down the road when you make more power.

I am going with the carb intake, but my build is a heavyly modified 408 turbo build. For the minor mods you are talking about at this time, save your money and do different mods. The reason I say this is because you can make more power with that money spent elsewere right now. More bang for your buck. You may reach a point were the intake is hurting your set up, at that time look to change intakes. I just think the performance gains in these factory replica intakes are realy not worth the trouble. Most of them are very minamim gains, if any.
When cold and not heat soaked...
To each his own, but I believe the guy who has one and posted above said something along the lines of.. "Its jut like your heads and block, it gets hot and stays that way for a while..."
That's enough for me to stick with an LS6.. The BBK would be easier to port I'd imagine though... and I guess if you're going to spray through it that the heat soak would be a little less of a problem..

Well thouse are dyno numbers were heat soak isat the worse. Ive done before/after right on the dyno BBK/LS6 both fully warmed up. BBK makes more power. You can also get more gains porting the BBK intake down the road, along with higher resale value. And on a well setup 346, h/c full bolt ons a 90/90 is only a few singal digit hp over a 85/85 intake setup. Thats is a lot more money, for what alot of people on tech think there will get with a fast90/90 on there 346
Well as usual ur probably not getting the answers ur lookin for, camaro468. There no best part... Sure everybodys says go wit the Fast setup, but in my opinon thats way to much money for as little hp ur going to gain. Swaping intakes is just like most "bolt-ons" you get a little for a little. If ur like me u will swap ur intake to whichever one ls6/BBK/LSX, and when its all said and done ur gonna wonder if it was really worth it. I mean u just dropped a few hundred bucks and ur car feels a little faster, a little....
But every little bolt-on adds up and before long u look back and remember the days when u could punch ur car and not have to worry about keepin it staight. Isnt it fun!!!
Anyways, since i seem to be the only one thats got a BBK, its a good product, it looks good, and is priced good. In my opinion it performs good to, but i dont have any before and after dyno pulls to prove it. It is heavy and gets heaksoaked fast. But does it still perform when its heatsoaked?? I think so, but i dont know?? If BBK molded this same intake in a plastic material like a LS1/6 intake, i think it would out perform all, hands down. But thats just my opinion...

well i got a idea on what to go with for now i just think the fast is way over priced and would not be worth it to me at this time i am just looking to gain as much hp with bolt ons for now before i get in to the heads cam for now
