Understanding the 6 pack CFM is one of the hardest things for Mopar guys. A really big percentage of them will never figure out the whole 2bbl flow rating thing. I gave up correcting people a few years back but I'm glad to see that you're still putting up the good fight!

The equiv flow rating of 900+ cfm is enough to make really good power, it is the twists and turns inside of the stock intake that kills the combo. Especially at high rpm and/or lots of cubic inches. But the setup can easily make 600 hp on a healthy short block so it does work really well up to a point. And that point is more power than what 99% of the folks need on a street car anyway.

Well said.

Another way of looking at it is this;

- at the 450 - 500hp level the stock six pack setup is one of the best setups available and makes more average power and torque than all but a couple of the best aftermarket intakes and 4bbls. It's far superior to the factory 4bbl manifold and carb yet people always want to compare the stock 6 pack set up to and aftermarket 4bbl.

- After that level, you are giving something up to run the 6 pack but that doesn't mean you can't make 650 or 700 hp with one as evidenced in this thread. It's kinda like headers; at this HP level, you'd be able to make more power with a good 4bbl intake and carb but it depends on how you view it: do you want max power for your particular engine or do you want to make your target hp (whatever that is) using a 6 pack.
