Best intake for forced induction...

Give me a couple of combos and which intake you feel is the best. If I built a 427/383/347" street car with any cathedral or oval port, its going to have a custom manifold from John on it. airflow distribution says its the best IMO.

Stock cube budget build I would probably say a LS6 intake...wouldn't be cost effect to spend 3K on a custom manifold from John or even a built 427/383/347 build that someone is planning on running hydraulic lifters and not planning on spinning it above say 6700 rpms wouldn't start to see the advantage of the sheet metal manifold.

Man it does not matter if you are spinning it to 6500 or 8500 it's about getting air equally into every single cylinder. Why do you think they have EGT probes on each cylinder? So they can see how the fuel and air is distributing as a whole and that one cylinder isn't seeing a drastically different condition than the other.
Now I agree a 3k custom intake manifold that takes 3-6 months to get isn't for everyone. Once you break that 9.5-9.0 barrier though and cross over the 900-1000rwhp mark which you are close too I know, you have less room for error when it comes to airflow distribution on these 25-50k motors. It makes the 3k manifold well worth it.
Phil when you say Tom, you mean Tom Kempf right? Has he got the high CR pistons in now that he is going to run M1 with?

Any idea if the intake that Marcella and Shawn were working on made any progress. It was supposed to be a cast peice I thought, and was a 2-peice intake split down the middle, it almost looked like the Edelbrock Proflo, just lower profile that seemed to taper in the rear.
Shawn posted about it a few months ago and said it should be available early summer and was wondering at first if this was the intake.

I was just reading in another thread you posted in telling a guy that his elbow and carb intake was going to grenade his motor by running the front cylinders rich and the rears lean because of air distribution with high boost. I wasn't aware of this until I read your posts. I find a lot of info very valuable in the F/I section from you, josh at ky, fireball, MM and so on. I don't know why some people won't take it from people who have obviously been there and done that more times than they can or would like to count.
