Whichever carb you're familiar with is best. Either is a good carb and can be tuned. I personally am more familiar with Holleys and would go that route. But if I had a Carter/Edelbrock expert in the neighborhood I'd go that way.

If you do go Edelbrock use the Thunder series (AVS) as you should be able to go up a carb size as the Air Valve will feed the carb the air it requires.
