If you have to have the choke out, it usually means a vacuum leak.  Check the hoilddown bolts in the intake and carbs as  well as any source that have vacuum or item that is vacuum operated.  Check all vacuum lines.

Could also be a carb float that isn't right.  Even pros make mistakes.  Running progressive linkage?

If You have a Vacuum Gauge most also read Pressure. U should be able to "T" into Fuel line between Pump and Car to verify Pressure.

  

The issue I'm having is: in order for the car to run I have to have the choke pulled out more than halfway. It has a stock fuel pump with a fuel pressure gauge. I have it set for 3 pounds. But it doesn't seem to hold a steady pressure I had a lot of times it will go all the way down to zero.

You need to first verify pressure and volume supply with a QUALITY MECHANICS fuel pressure tester.

What are You using for a Regulator? Try running without Regulator and see what that does. Maybe Carbs are not getting a Constant supply of Gas if the Gauge is reading correctly.?

  

Got a rebuilt y block, it has "trips".
3 Ford script "94". The center carb.
Has choke, 52 jet's. The 2 out board
No choke 49 jet's. The carbs or just rebuilt by a well-known rebuilder. The issue I'm having is: in order for the car to run I have to have the choke pulled out more than halfway. It has a stock fuel pump with a fuel pressure gauge. I have it set for 3 pounds. But it doesn't seem to hold a steady pressure I had a lot of times it will go all the way down to zero.
So what do you guys think about me having to run with this choke on?
Thanks
