I have a high presure Edelbrock mechanical fuel pump rated at 10 psi on my 347 The holley 650 max operating pressure is 6 psi so i installed an adjustable holley regulator and set the pressure to 5.5 psi and have not had any issues at all using the standard float height measurement I also installed a $10 fuel pressure gauge inline next to the carb so you can watch the pressure while adjusting the regulator. If you had a fuel pressure gauge you could see at a glance when you are at wide open throttle , maybe you could monitor that and see what is happening.

Goodluck.
Al.

I thought I would post a follow up to this old post. I installed a fuel pressure regulator and shut the fuel pressure down to 4.5lbs. The problem went away immediately, I raced the rest of the year and never had anymore trouble. Thanks for all the help guys.
