Dual quads versus big hammer!!!...

Everything I'm reading says the vacuum keeps the rods down at idle. And generally speaking their thinking you have the same vacuum at a steady cruise at low RPM. When I check my charge for my Edelbrock so I use the yellow spring. But again remember they had bigger primary so they weren't trying to suck it from such a small hole like these smaller Street demon primaries. So I feel I'm getting more vacuum with these carburetors.I've been trying to jet down enough to not have to turn the idle mixture screws in past 1 and 1/2 turns but again like my Edelbrocks in near 3/4 of the turn to 1 and 1/4 turn. And I'm at about 1 turn to 1 and 1/4 on all of my idle screws. the first thing I'm going to do is get it warmed up and take it for a short drive tomorrow and then just start putting fatter or stronger Springs in and see what happens now that I seem to have this idle and everything else under control. Also I do have those 31 squirters up top and I can put stronger squirters in as well to see if that helps again.
One more thing I have is those metering rods coming the 58/44 s and 58/50 s...
Again that article States putting richer rods in the front carburetor...


I can buy the front carb running a bit fatter. Fuel does move around in the plenum.

Blown alcohol has a huge stagger. When they stage you can see the front holes dropping every now and then because they are so fat. When the blower gets going the fuel moves to the back. And the MPH adds to it.
