In all fairness, this notion "eddies work out of the box and hollies don't" just isn't right. I've bought new holley carbs and never had a single one that didn't bolt on and run real good right out of the box. The only difference is, with the holley you can fine tune good in to great (that last tenth at the strip you were talk'n about). Just because you have more tuning options with a Holley doesn't mean they don't run good out of the box. However, I've had eddies that couldn't get rid of a bog out of the hole, and not enough tuning features so I had to ditch the carb... for a holley and tuned the bog out.
