How many turns in does it take to lightly seat the idle mixture screws?

I find Edlebrocks tend to like the idle mixture screws around a 1-1.5 turns out from lightly seated.

And to that, how big is the cam in the engine, because it's possible it may need more RPM than 750 for idleing. 750 RPM at neutral idleing may not be enough for when it goes into drive. Do you know the in gear idle RPM?

Also a super tight converter on a biger cam will really drop the RPM in drive and make it very hard to drive around the idle range---for example a small block with a stock stall 904 converter fighting against a mopar 292 / 509 purpleshaft cam. This an example of one I worked on for someone else. The car was then speced for a 3600 stall converter by a well known company and all the other drivability issues disappeared.
