Time to talk a bit about Edelbrock RPM intakes, Holley Street Avenger carbs, and air cleaner fitment issues on a 440 in a Charger. I am also using a .25" carb spacer that gave the motor another 15 hp on the dyno. This is the best I have found so far and would appreciate any other options that you guys are aware of. Here is a shot of a Proform 1.5" drop base siting on the carb. With the top that comes with this air cleaner, the hood wont close - and it is butt ugly imo.

You can see how tall the choke horn is on these carbs. I am concerned with airflow, so I had this stuff milled off the carb.

Here is what it looks like now. I then bought a Holley air cleaner that comes with a 1.25" drop, but only used the top and filter. I still can't use the supplied stud nut because it is to tall. I put a flat washer and nut on the stud cut off as short as I could. This leaves me with .75" from this to the bottom of the hood. I have a hood pad insulation that I want to use, but am thinking it might not work. My restricted area from the top of air cleaner to the bulge in the base leaves me with 3/4" of air flow around the opening of the carb. I wish this was more, but as of now that is the best I can do and still shut the hood.
