That's on the 440 six pack.

your altitude is a big factor in air flow and efficiency ...a problem I face here at almost a mile high ...the oxygen just isn't around like it would be at sea level
you all best stop, you're making me want a 6 pack for my 440 lol

I just found this on the same site.
Outboards are 500 cfm, center is 350 cfm. Measured at 4" Hg pressure drop. As opposed to 4 bbl that are measured at 2" Hg pressure drop. Divide 2 bbl figure by 1.414 (square root of 2) to get 4 bbl equivalent (955 cfm in this case).

My plan is working!!!

Yes, but the ratio of total cfm at various rpm is very different for a 4 bbl vs 6x2bbl. On the 6 pack, the low rpm flow is much less than on an equivalent cfm 4 bbl.

Ok, so because of the delay in opening the outer carbs as well as the jetting on those outer carbs that is how they can run 960cfm on a smaller cubic inch engine?

Ok, that makes sense... kinda.. Im going to have to absorb

Well thank you all for this mind boggling explanation.. I've seriously been trying to figure this out for the past couple of weeks.
my head hurts now, thanks

Chris, I just watched that video on that ammo. Holy Crap, that is insane. Lehigh sure did make a round that penetrated.
yep, imagine that loaded to +p

The simplest way to think about it is this...
By using three 2 bbl carbs that open at different times and are jetted differently, the total airflow and A/F ratio is optimized so that it is never oversized at low rpm and never flow restricted at high rpm.
It would be like if you could use your 600 cfm 4 bbl at low rpm and then switch to a 750 cfm at high rpm.

That does make sense Dave. Why didnt you just say that to begin with??? My gosh you just had to drag it out

LOL! I guess it's the (NUTTY) professor side of me. I always teach students by feeding them bits slowly to get them to think their way through it and find the answer on their own before I just give it to them.That does make sense Dave.

he is obviously quite self aware.. 
off to go run.... *glup* cya later
so after taking a good look at what I have to work with ....it's not as bad as I first thought
basically ...this is the most important of the bracketry that needs re-conditioned because it is very 4 speed specific ...the hole is enlarged which needs fixed and the pin can be ground out and re-set in place
the reason the 4 speed specific bracket was thrown out of geometry is because of this bracket which is trashed but is coincidently the same piece as on a automatic brake pedal, so its going to be easily replaced with another copy off of any 65-8 C-body automatic brake pedal
