Has anyone here ACTUALLY done a supercharger on a 4.0L OHV engine? Reason I ask, is cuz its looking less and less likely for a 4.0 to 5.0 swap in my '91. I want lots of power in my explorer, but still want to keep it a manual transmission. I hate automatics. How hard would it be to do the SC on this motor, and since this motor has 198K miles on it, I would be rebuilding it once it goes.
