I have set the float level from bottom of the sight glass to 3/4 with no apparent change.
The car runs fantastic in all rpm ranges. The only issue is stalling.
Any suggestions?

No suggestions to your problem, but my road race car with a 650 Demon has done the exact same thing from day one, I've tried re-setting the floats and a few other things and nothing really helps..... the only thing I do is downshift and brake while the clutch is out so the engine keeps running.....
BTW: my street car,65 fastback with a 600 DP Holley DOES NOT do this!!!!!!!!!!!!!!!!!!!!!!
I have no clue or answer...........
