Edelbrock Experts I need your thoughts

Your engine is very much a performance engine. The 1406 may not be tuneable for you. That's what I was trying to get at.
Oh sorry, I gotcha now! I did find a thread about some modifications I could make to it, but I would rather get one of the AFB carbs if that is the case.. I dont want to mess up a carb that someone else could use. I do have to say, though if Im just cruising around (easy on it) with this carb, the car runs great, is smoother, and my fuel mileage is much better.

Is the lean mixture effect momentary like a flat spot just after going into the pedal, or sustained weakness?
It starts leaning out as soon as I start pushing on the throttle and will keep raising as long as I keep pushing. Until either I get into the power side or I stop pushing. I've seen it from my cruise A/F to about 16.7 with a heavier pedal.

Now the WOT is another issue. If I hammer on the throttle it will go instantly lean (off the meter lean) until the fuel catches up, then its perfect. 12.5-13.0. If I roll into the throttle then mash on it I only get a lean spot for a split second usually the meter is around 16.7-17.
