Dialing in a Carter AVS

Hello Folks,

So this past weekend I was finally able to break in the 440 for the 70 Charger my old man and I are working on. So my dad is very old school and sadly the term "cant teach old dogs new tricks" resonates very well with him... With that being said he was adamant that he never heard or had to break in a cam before, even after I showed him the break in procedure from the cam company he was still reluctant, but I did it anyway.

With that being said... we are running a Carter AVS (not to sure of the part number, silly me didnt check before I left...) because those were the "best carbs around". So trying to get him to switch carbs is going to be more hassle than it is worth. The engine is a fairly stock rebuild. It was bored .020" over and has a hotter cam in it. I have the cam card, just not in front of me at the moment. What I do know is the valve springs didnt change that much stock, so I know it is not overly wild. My question is if I could use the Edelbrock calibration kits to help dial in this carb to get the most out of the car? and if so which one? I have heard you could but really couldnt find much information out there as to which kit to use. I believe carter had these strip kits back in the day, but finding one is difficult and I saw the prices are astronomical.

I believe the AVS is a 3 step metering rod and the edelbrock utilizes a 2 step rod similar to the AFB. What would be the disadvantages/advantages of switching the AVS over to the 2 step rod set up?

I am just trying to make sure this engine runs right and I dont have an overly lean or overly rich running engine that would only cause maintenance head aches down the road.

Thank you
