Adjustable jets are too inconsistant--
One of the best things about holley is that the jet numbering system is flow related, not hole size
Now other than that---float bowls that have the holes to change holley jets without removing the float bowls are a nice deal in that its easy to remove a plug and drain high octane fuel on a hot engine--- but at least you don't have to mess with the fuel lines
