Stop in for a cup of coffee

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

one word:

Turbocharger=problem solved, your welcome
 
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).
 
That is essentially what a 4 barrel does though correct? The primary opens first then the secondaries follow.
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?

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:poke:

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.

Why would you say that about yourself?? LOL Nutty!
 
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
