Edelbrock carb adjustment

Some good info here when the Eddie 1407 was discussed on SpeedTalk

Edelbrock 1407 - Don Terrill’s Speed-Talk

If the Carb is calibrated right there should not be any real issues. Boosters in the the Edelbrock 750 are too short and need to be lengthened like they were in the original carter carbs. In Short find an old 750 Carter and swap the boosters over.
