i can get a 5.4 4v from a 99 expedition for only 125$. i was wondering if any superchargers will work with this. like mabey the lightning super or something else
Then it's not an Expedition, it's a Navigator. There's no bolt on option out there for you. Kenne Bell made a Navigator kit years ago, but I doubt you'll be able to find one. Any supercharger setup would require large amounts of custom fabrication.
Towing, and performance. Have a 4.6 now
There are superchargers for the 5.4 4v stangs will that work?
