Currently playing around with hooking on the air filter on my 71 charger with a 440 in it. My car has an air grabber on it and the base is different than what I am used to. I have had trouble digging up a lot of documentation and have a couple of questions.

1. I am not 100% this is the right air grabber base for my set up. The car originally had a 383 in it but now has a 440. Is there a way to verify that this is the correct base? Do I need to worry about height between the different engines

2. There appear to be 3 places for hoses on the base. One currently has a hose attached but then there are two other nipples at the font of the base. Reading around I think all three might be drainage hoses but having 3 of them seems excessive.
