Guys,John and i measured a 5in top AFB and a 4in top AFB today from base of the carb too the air cleaner base on the carbs.The 5in top AFBs are .825 shorter than a 4in top AFB.This will help with your shoice of carbs if trying to get them under a hood.AC height will need to be added.As I said before that a 69 T/A intake screen will be the lowest to use.Tom
