Edelbrock makes several 1400 series carbs, but the most common is the 1406, which is set lean to get good fuel mileage. It would run with your engine, but it would not be a good match for this cam.
Also, if the owner used a HP fuel pump, verify the fuel pressure stays within Edelbrock's recommendations (5 psi?). The 1400 series does not run right if the fuel pressure is too high.
Its quite easy to swap rods, jets and springs on a 1406 to tune it to run better for high performance. However, without an AFR and some other tools to see the effect of your changes it will mean a lot of experimentation before you get it right.
Instead of tuning the current carb it may be simpler in the long run to swap it out with a Holley or one of the other Edelbrock carbs that is a better match to the rest of the engine.
