what engines will interchange with 1999 explorer with 4.0
I'd stick with the same size 4.0L engine, as it will bolt up to your transmission and work with all your other components/accessories. Just swap the parts over. Any other engine you will have to do some customization which = $$$$$. Make sure you get the right 4.0L as there is a OHV and a SOHC version.
i have a 98 explorer as well would a 4.0 out of a 91 ranger fit into my 98 explorer 4.0 stick?
