    so the cougar cam could go in the explorer motor? (but then which EEC would i need?)

    so are those "tubulars" the stock manifold on any '90 towncar?

    thanks for the tip... these are the kind of details i worry about trying to pull this off.

    also good to know! hell, a big reason i'm even considering this is because my current pan is jacked.

    not sure i want to google "threaded dingus"...

    hmmm... decisions, decisions.

    If you're rebuilding, it won't matter a great deal. Still, if one seems to be obscenely well used, skip it. If its too horribly beat it may need a bore job or a crank replacement or something. If it looks like its been rolled, I might pass on that too. I had an intake off a rolled Explorer that had cracks. They were welded up and it was functional but skip that nonsense if you can help it.

    It can. Stock mass air Mustang ECM would control this OK. It would be more OK with some tuning but it'll certainly run and be drivable without it.

    so are those "tubulars" the stock manifold on any '90 towncar?
    Yes. One year and one-model part, but all of them got it.

    Any Fox oil pan also works. They are the same as what we got. The magical Mustang 351 swap oil pan is in fact a Crown Victoria part. The one single part our cars have donated to the high performance world

    I think its officially named an oil filter adapter, but you've seen it. Remove the oil filter from your car, and its the thing sticking out of the block that the filter threads on to. There is a big hex nut at the base of it, and if you cuss in the right language you can un-screw that from the motor. the Explorers just have the threaded hole in the side of the motor because the oil cooler mounted on that way. Its more or less a pipe nipple, though I don't believe its pipe thread on either end.

    Post to summarize thus far...

    okay, mostly for my own good (way too many factors rattling around my brain!), allow me to think out loud:

    option 1)
    a near-complete, running 5.0 from a '90 Mustang with 55K miles (sale would not include exhaust or harness/EEC).
    seller reports leaky rear main, but otherwise good -- still in car until sold so i could hear it / drive it.

    for this i'd need to at least do seals / gaskets (so probably a rebuild kit anyway); find a '90+ harness and EEC (only from mustang, right, since it would be MAF?); and (if i recall from other threads) "flip" the upper intake and so some minor mods to throttle / TV.

    pros: low-ish miles, MAF, "car" engine, seller would pull motor
    cons: not as much potential as explorer swap, more $$ than option 2

    option 2)
    a complete junkyard motor from either '96 or '97 explorer, potentially for about $175 if timing is right.

    for this i'd need a harness and EEC from either a '90-'91 panther (??) or '86-'88 mustang ... <-- not completely sure if that's right -- but there's a chance it would run "stupid" with SD, so alternately would need to upgrade to MAF from '89+ mustang instead
    i'd still need the rebuild kit, and would need to also replace springs in GT40 heads. i think this upper intake also would need to flipped, etc. also need oil pan from panther or fox.

    pros: better internals, better heads, better intake
    cons: technically "truck" motor, but i could pass it off (kinda) as a '93 mustang; MAF-conversion on top of swap; i'd pull motor from yard

    in either case i need a new timing cover. i guess in both cases i also need to address exhaust. (so we'll call that a wash.)

    what am i forgetting (or getting wrong)?

    looking at my own post above: if i went with option 1, i suppose i could upgrade to explorer heads, right? additional $$, but the MAF / EEC would deal with it, right?
    also, my harness would need to be '89-'95 mustang, right (before they went to OBDII)?
