I use a in tank electric fuel pump, sending, hot wire harness and gas tank for a 87 Buick Turbo Regal. 1/2" lines tank to Robb MC regulator, 3/8" line to carb with a 3/8" return. I run about 9 lbs pressure at the regulator. Have to get a gauge at the carb.

Are you running 9# all the time, or decreasing pressure at idle/high vacuum? Care to share what specific regulator you are using?
What CR is the engine?
CAm?
I know I can do this and appreciate you sharing your experience.

The one thing I'm thinking is going to be hard is getting enough shot from the accelerator pump. All of the Holley carbs I have seen on circle cars on E85 have 50cc pumps front and rear.
