You guys mention that the new Holley Carbs are set way to lean out of the box. Based on my specs listed below how would you re-jet initally before installing the six pack setup on the car?
I'd leave them alone until they are on the engine and running, just be aware that they might be on the lean side, every engine has different fuel needs, trying to nail down accurate jetting and fine tune settings prior to running them is nothing short of guessing, plus your combo is fairly mild, the out of the box settings are a good place to start as a base line.

I've always knocked the seal plugs out of the front & rear carbs & backed the idle mixture screws out 1/2 turn...

and finding jet plates for the outboards are a pain. if geting really radical, you can driil and tap the jet plates for replaceable jets. just make sure you plug the holes on the bottom of the plates

Who has the set up for $2200?
Did you use the kit from this supplier?
Joe
I got it form Atlantic speed.
http://stores.ebay.com/AtlanticSpeed-Performance-Parts
with my 100 off e-bay coupon I got mine for under $2100 plus shipping. He even shipped it all to my friends house so the Mrs wouldn't see all the boxes...

It is used to set engine idle RPM. Chrysler had a run on issue, I can only assume, so the easiest/cheapest way to fix it is to have the butterflies closed completely when you shut off the engine. The solenoid is powered up when you turn on the key and it open the butterflies, it is what you are supposed to adjust to set idle speed.
With a 4 speed car I have always gotten in the habit of slightly leaving the clutch out as I am turning the ignition off. (Kind of like stalling the car out by leaving the clutch out too fast and not giving it any gas). This will not allow the motor to keep running after you turn the ignition off.
If this is all the idle solenoid does, then I cannot see spending the extra money for it.
Any thoughts?

 and as said before,you might need a new air breather to your passenger valve cover with a extra connection on it 
My current air breather only has one connection. Where do I buy a new air breather with two connections?
Thanks, Rob
