Generally out of the box they tend to overfuel and need leaning out.If you search these forums there's a few suggested known rod/jet combos that will get you close.

Essentially you adjust the rod/jet combinations richer or leaner in the idle/cruise areas and the wide open power areas. You can get a complete rod/jet kit to do the calibration yourself. This PDF explains how to adjust the calibration in stages richer or leaner (page 10)
http://www.edelbrock.com/automotive/mis ... manual.pdf

It's a 4 barrel carb, initially you are focusing on calibrating the cruise/power mode - which is the combination of rods, jets and springs against the primary throttles.
When you floor it (WOT) the secondary throttles open up which have simple jets - which you can calibrate up or down accordingly. Only adjust the WOT settings once you have cruise/power mode sorted.

Using a wideband lambda sensor you can verify the results yourself - which will cost less than paying someone else to do it:

I've been over to a rolling road in Doncaster DN12 2AQ, chap named John Sleath.

He is conversant with the weber, and has all the tuning kit, control rods jets etc.

Yes John is reputable - give him a buzz first though to make sure he's familiar with the Edelbrock carbs, would be suprised if he's not.

From memory he does know these carbs, years ago I was going to use him but in the end I purchased an Innovate LC1 and learnt how to setup an Edelbrock carb myself.

I should have put that he is conversant with the edelbrock, and not called it a weber. He tells me that he knows them very well and has set up many of them.
