Howdy, I hope this is the place for this question, as I was unable to find a more appropriate place. Of course, I may be the only idiot to need this help. When I search on, say in the "Instructions & Manuals" area for example, it says to enter the Holley part number or list number to search for matching documents. When I enter the list number of any of my carbs, I get around 2,500 results. I confirmed that I was entering the correct list numbers, by checking my numbers against the numerical numbers list. I entered the info exactly as it is both on the carb and as it is on the list on The more info that I enter, the more results I tend to get. If I add 4150, or 4150 4BBL or whatever, it is of no help. What am I doing wrong? Thank you for any help.
