Holley 750 stalls while hard breaking

I had this same issue on my 340 with an 800 cfm Edelbrock
Beat my head against the wall for dam near a year floats, rods, springs, settings, jets. Finally figured it out the old rule of thumb to set the mixture screws for highest idle and then go a 1/4 turn rich is a bad practice - stalled under hard turning and breaking everytime.
Now I set the screws for highest vacuum and the go a 1/4-1/3 turn lean. no issues

Oh cool! I am having this problem now on the wife’s car. I know it’s ether the floats or the idle screw settings. The “Job” is incomplete as it was just put on and rough tuned. That and the distributor. I’ll get to it later. A bit busy now with other things. But that was good to read.
The carb is a 600 Edelbrock which is way small for the Hyd roller cam, TF headed 360.

Looking forward to a Brawler later on.
