I'll add: doing as said above, and getting a tune for the car will Really wake it up.
Dual exhausts and an x or H pipe will help, Mandrel bent exhaust parts can be had cheap. Sound is the biggest diff in the X vs H pipe, IMHO. I have X pipes.
Get a tune, I'd recommend Don Lasota, of Lasota racing.
If you can pick up an UNLOCKED Xcal2 from ebay cheap, it will save you cash; I bought a few for $100 or thereabouts.
Note the caps, I'm not shouting, lol.
That will make for a nice DD.
Search for additional mods, there's a ton.
As was said, An aluminum Explorer block drops a Bunch of weight, IF you're doing an engine swap, that's the way to go.
