Dual quads versus big hammer!!!...

What was the idle speed for that idle vacuum??

Keep working with it.

It may be either getting on the mains too late or, you need to get the metering rods out of the jet quicker.

How to accomplish this with those carbs I can't say. But it can be done.

Well, you change the set up spring to get the metering rods up quicker.

If you can drive it, see what the vacuum is at a cruise. That would be interesting.

900 idle speed..
I've been paying way too much damn attention to that O2 sensor I'm trying to get the idol up to 14 2 to 14 7.. I've been going softer Springs and getting no change, so tomorrow I'll try stronger Springs and trying to get those metering rods out of the Jets...
I'm going to recalibrate and try the O2 sensor with that new cheap Amazon sensor and try the old one as well and if that doesn't work I'm just going to buy the new Bosch one.. It use to work and it was spot-on... Everything I'm reading on tuning these highly recommending one. And that's pretty much what work for me to get the Edelbrocks sorted out..
