There was a myth that the stock manifold caused the lean failures of piston no 7.
Despite that the same problem occured when someone tested the stock manifold in a reversed position.
If air was blasted totally vertically into a carb intake, then perhaps it might be even.
with an elbow...I'd be less than convinced its even at all given the turns it has to make to get into the manifold.
A large open plenum, feeding nice straight runners has to be good on any boosted application. And probably n/a in terms of airflow...altho throttle response might suffer due to the large volume of air behind the throttle plate.

They are referring to the old X pattern that was used in the 98-00 cars. The 01-02's with the LS6 manifolds only had a cross over from the front of the 2 heads and the rear ones are blocked off.
Back on the original subject... I think I'm gonna pre-order that new manifold from summit. It shows a ship date of 2/2 if ordered today. I am planning on taking my LS6 manifold off tonight and gonna take some measurements to see what will need to be done to get it to fit. I don't mind cutting the cowl. As long as I don't have to cut into the wiper arm i don't care. It looks like I shouldn't tho since the base of the arm is offset towards the driver's side a little bit. Also the width of the top part of the manifold only looks to be the same as the TB, so it shouldn't be too wide of a cut.

All of you guys that think a centrail plenum( carb style) are not any good you should send Tony Christan , Pat musi , Tim Lynch ,Steave Petty ,Derick and Dennis Baily, Billy Glidden and almost every outlaw car builder , That they would finly have a engine with equal air flow if they would go to this type of intake I think this intake will work but most oem are this way is for hood clearance not performance

As far as i can tell, i may be missing it but summit doesnt show thi manifold for ls based engines yet. And when i spoke to a rep from Edelbrock its still in r&d and to give him a call in late february

I think they were 30-35% difference in fueling from the frt to the back of the engine to compensate.
None of these intakes have even distribution in a f/i application out of the box,but it is much easier to mod a sheetmetal style intake for better dist.
I've spent countless hours on the flowbench and dyno to get better dist in my own stuff.Right now i'm working with John Marcella of Marcella Manifolds to get even better dist out of the intake for Phil's lsx as well as my new 670bbc.
