Eldelbrock performer mechanical fuel pump

[Beekeeper]

Has anyone used one of the Edelbrock performer RPM series big block mechanical fuel pumps?
I was looking around online and see they have a 3/8 inlet and outlet and are indexable.
Was wondering if there are any pump to block clearance problems and overall general performance.

Used them a few times with no issues , but make sure of the fuel line size from the tank

No pump to block clearance issues. Mine makes 8-9 lbs even though they advertise 6
