This is what's happening.
I have a 500 2 bbl. Going to set it up for the blow thru tests. Should be able to provide plenty of fuel and airflow.

Thanks all for taking the time to consider your options to help.

Found out that 450 carbs did not come with double squirters, some did come with mech secondaries for blower use. I needed a carb with double squirters and mech secondaries. 600 double pumps are easy to find but are just too big for a 250 motor. Tom
