Air Grabber Air Cleaner
If it helps... My six pack lid just makes it under '69 Barracuda hood. The base is a shaker, less the adapter and has just a slight bend down (not cut out) on the driver side rear to clear the wiper motor nose which almost touches the filter element. I'd worry about a grabber seal there for sure. I guess a 3 speed wiper motor may provide enough clearance. I've not tried it yet but I have my old '72 440 round element air grabber cleaner if I ever go with a 4 barrel. I've seen some non-fresh air six pack bases cut out to fit the two speed motor. I imagine the single 4 would be similar though.
