Project Big Block 74

just run a drop base air cleaner. There's guys on here with 440s that are clearing stock hoods with the drop bases. I would not recommend the cowl hood. For one, they're ugly as hell on a mopar, the lines just don't work. And 2, visibility is greatly affected, to an annoying level.
The drop base works with the rpm? I've heard they sit high and cause issues closing the hood.
