Intake manifold idea.... I have been kicking around this idea, just wondering what folks in here might think. We all agree the stock manifold is restrictive. But, what is the problem. The runners are too long, and the box is too small.
So, how do we fix that.
Well, SAM cut a manifold all to pieces and never found much flow gain.
But I got to thinking about it and an idea came to mind. If you cut the floor out of a manifold (say an LS6). Then you look inside, you see that the runners come all the way across the manifold and open up on the opposite side. They are all joined by a common plenum.
My idea. Cut the floor of the manifold out. Then simply begin cutting back the runner length. In fact you could most likely move it all the way across the manifold to where it begins. This would hav the net effect of shortening th runners and increasing the plenum size...
Just a thought...

Re: Intake manifold idea.... If I'm not mistaken, Terry Burger did this already, and lost 20 rwtq and gained no hp.
I think this is what he tried, anyway.
You can see this concept easily by looking in the bottom of a Holley intake.
