Not Ranked

True, but most from what I can see have changed to the one carb and turkey pan set up due to a few reasons.
1-The real comp cars ran that way.
2-The one ran better than the 2 and was more consistant.
Most engine builders have experienced that the 427's short-falls are not in the fuel quantity and delivery to the intake. Rather, what to do with it once it gets there. You can bring in all you want but, if the heads can't get it out via limited flow exhaust ports then you did very little to power enhancement.
The original single 4 was 780 cfm that took air from an air cleaner that flowed about 350 cfm. That carb was still a bit too much. I raced with a trick 750 cfm. That was all the engine needed with 12:1 and very worked heads. Anything after that lost power. More is not always better and if you didn't see it on the dyno, you just can't tell from the seat of the pants. There is nothing to compare it to.
