Default Intake manifold flow charts

I remember seeing a flow chart on here before, but could not find anything in the search...

So does anyone have the link for LS1/LS6/FAST/other intake manifold flow #s?

I thank you for your avatar

Edit: Actually...does anyone know stock LS1 intake flow numbers, since that one doesn't list it?

I would have to assume it is below the eldebrock "high side". Those must be SBC intakes on that chart.

I hate to revive an old thread, but the site hosting the picture for the sticky was shut down only a few days ago. Does anyone still have this information?

Not that chart, the picture with several manifolds tested with their flow rates in a vacuum. Fast, ls6, something else. Anyone else know what I'm talking about?

I know what you wanted; it's gone. So, I thought the link I posted might help.

Old chart showed highest to lowest flow from sheet metal to Edlebrock in this order:

1) sheet metal
2) ???
3) FAST
4) LS6
5) Weiand
6) Edlebrock...
7) Edlebrock...
