Stock Intake manifold CFM

Has anyone ever put the stock upper & lower on a test bench to measure its air flow (or even just the lower)

I don't want to put the cart before the horse, but I am pretty confident I'll run an 8 or real close to it with my stock upper and lower intake. I know my motor is making over a 1000hp, and I still have a lot of room to turn it up. When I get some EGT data on each cylinder I will post it, should find out which one is the leanest.
Probably not the answer you were looking for but I will have some data. that might help, in the next few weeks

Good Luck with running 8's I hope to see you and your truck at the Nats this year.

I would be interested in seeing that data as well.

If you can get EGT readings on each cylinder...that will tell a story that been missing forever on these intakes. That would be a great thing!

Good luck on your times...you can do it!
