6 Pack vs. 650 4BBL?

The biggest problem I see here is the comparing of the stock style Holley 2bbl. carb trio to the heavily modified race Holley. (This is also a problem between the Carter/Edelbrock vs. Holley)
CFM wise, the 6 pack delivers in the 950 area cfm of air and fuel (when the conversion is made). VS what ever 4bbl. your putting it against. Just on cfm alone it has the ability to make more power. So the next thing would be...

The 6 pack intake could be updated to a more modern well thought out design. The small block intake has 3 towers! That go down to a the dual plane runners. Air and more so fuel do not like to take turns. And there are 90* turns involved.

This ancient intake could use some modern help!

The modern 4bbl. intakes have only 1 disadvantaged to them and that would be the central location of the carb. The air and fuel have to make a long turn. And it is far better than the 6 pack! And only 1, but not so bad over all 90* turn.

Between a single plane and a dual plane, the single should be easier to modify and correct to equalize the flow to equalize air and fuel mixtures over the dual plane.

For a intake released in ‘70, (small blocks) it is still a hell of a Performer.

You wanna go fast? A single carb on top of your intake is the easiest and cheapest way to go.
If you want WOW, pizazz, BAMM! flexibility for your street/street stripper and the money is not a concern, a 6 pack is it. Dual plane dual quads are also a very do-able way as well. But are super difficult to find.
