LS6 Manifold Differences
If you want to get technical then, I'll point to the part in bold above. This statement is correct for the most part. It is about differences in manifolds, possible differences between LS6 manifolds. I never wanted opinions on FAST, BBK or any other type of input whatsoever from anyone. Not my fault you're a FAST 102 
and had to pipe in leading to the downward spiral this thread has taken.

Or you're the ignorant one for always saying the FAST 102 is the end all be all of intake manifolds. I'm not saying it isn't if you're looking at them in general, (actually even then it isn't considering custom sheet metal intakes will outperform them), but I've seen numerous threads where you wantonly throw out that the OP or other poster should get a 102 when they may not need it and that's just stupid. If you can't make full use of it DON'T GET IT. If it may be beneficial but you think it's too much money, DON'T GET IT. I'd be in the latter category.

True, I did say before I found that one LS6 manifold that I was planning on getting a BBK. And looking back at it before all of the arguments started, it was YOU that really were the catalyst to it all by saying not to go BBK, go FAST. You could have just let it go and the thread would have been a success and it would have ended.
Point is, if I don't find a good deal on an LS6, which are all the same, I'm getting a BBK unless I find a FAST setup with manifold and tb for under $850. Any more than that its not worth it imo and the BBK will be best bang for the buck.

For me it all comes down to combination; You can t be choosing between an LS6/FAST/BBK and a sheet metal intake at the same time. They are WORLDS apart. But when you concider the street manifolds the LS6/BBK/Lingenfelter/etc are all fairly close. The FAST shines over them all, but it costs more. Pick your poison.......
Budget; get LS6
Max power; FAST
RACE only (trailored to track); sheet metal/tunnel ram style

I think that sums things up nicely. The BBK just sits between the budget and max performance, people hate on it because it's metal and thats not right. I do understand that a sheet metal intake is beyond most applications, I was just trying to make a point that all things considered while a FAST is generally the best for overall performance there are exceptions depending on application.
No no no... All I said was get FAST... not to get BBK... Didnt compare them... Because that would be a Complete waste of time... YOU compared LS6 to BBK... like I said. We are talking about the differences between LS6 intake(well I'm glad you know there is none now) not which intake is better... Let this thread be done..... As offfff......... Now!

I HAD A BBK ON MY CAR on my previous mild H/C setup. I switched BACK to a LS6 with a ported stock throttle body and picked up power, throttle response, and idle quality. My father just picked up a LS6 intake off Baltimore's Craigslist for $270, so the deals are out there! But go ahead and get that BBK intake. Maybe you can get it in a package deal with some Patriot heads, an EBay reground cam, and a Fuddle converter.

An LS6 intake is an LS6 intake. There are no power differences between one that comes off a F body vs Y body.
BBK intakes are NOT better than the LS6. Heatsoak DOES exist and DOES affect intake charge temperature. The BBK throttle body IAC passages are terrible.
If you want to upgrade your intake and keep it under 6500rpm, consider the LS6 or the FAST, and nothing else. If the price of the FAST seems steep pick up a used 92mm and avoid the fuel rail cost associated with the 102mm.

Its not important to be right, but to convey correct information and dispell incorrect information. Especially on this forum, 1 or 2 people say the wrong thing and people start saying it themselves and everyones starts believing incorrect information.Actually probably 95% of the time the FAST is correct intake and the LS6 is 2nd because of budget concerns, so the statement isnt without merit. Will they? VERY few people on here need or have the ability to take advantage of a sheet metal intake. There is a lot more to look at than peak dyno numbers at 7000+RPM. It all depends on the combination and intended use of the vehicle.See my first statement about incorrect information. Here is a perfect example..... A stock engine benifits greatly from a FAST, a modified engine benifits from a FAST as well.

Good luck.

Before this thread is closed out can we get back to the topic ,differences of LS6 intake. What are you are calling ZO6 , casting # 12573572 . I have also read of the F body LS6 having slight better gains.Can any one verify?
^^^ ya BBK looks ok... But as far as Plain Black Plastic... You can easily sand them smooth and paint to match your car... Or your theme of the car. Thats what I did... Check it out.
