GT40 heads and PCM

[TecNickal]

Have a factory h pipe and factory tail pipes for dual exhaust. Have a stack of Lincoln Logs in my garage.
Once I get my garage cleaned out I'll attack this engine project next

PCM I can acquire now.

If you need any help, give me a ring. I can also keep an eye out in the junkyards for any suitable donor vehicles.

The 97+ engine isn't the end of the world. You need different headers or you can make it go with 1990 lincoln logs. Looking very specifically for a 1 year 20 year old engine is not exactly the easiest thing. Consider they stopped using that motor 15 years ago now, the supply is already shrinking.

Was a mid year changeover on the 97. Actually the only GT40s I've found have been in a 97.

There's an absolute shitload of 5.0 exploders in the junkyard local here. Too bad I have no use for any of that junk.

Explorers had GT40's in 96 and early 97, from mid 97 on up they were all GT40P's.
When I did mine It wasn't just the exhaust that was a problem, the 97 lower intake was not as plug and play as I wanted/needed.
I did try a set of Lincoln Logs on "P" heads back then and was not happy with the fit on at least one side.
Using the 96 made things a lot easier.
And I still see many 96 GT40's in JY's.

The lower intake you need to drill and tap for the ACT sensor, but thats true for all years. I believe its 3/8 NPT. Unless you have the funny size drill bit and the tap, it might actually be cheaper to drop that off at a machine shop to have done. You'll probably spend 40-50 bucks on the drill and tap, and lets face it, the chances of needing it more than once are pretty slim.

The later ones had no EGR, not the end of the world if you don't have emissions to deal with. I have EGR on mine, it even works.

To make the exhaust work right though, you want the headers that mate to P heads. Other things do fit, not ideally, but you can jam it together.

I was told that an explorer 5.0 can be swapped easily without any modifications. Quite literally, pick it, and install. Is that real? I'm not including exhaust in this. I know that'll need to be figured out.

Pretty much, need to swap the timing cover, all the accessories, water pump, etc..., oil pan, flip the intake, lighting EGR spacer, put in a decent cam and valve springs, 19# injectors, Mass Air swap....

But all and all, it is a direct bolt in swap for the most part. Best way to go to be honest.

[gadget73]

Its the best factory engine Ford actually made in a lot of respects. Cam is not amazing, but its got pretty much the best heads and intake they made, and there is nothing wrong with the block or rotating assembly. The valve springs suck, cam is meh, and the other bits just don't fit. They can be swapped though. A lot of the parts you'll need are already on your stock engine.

[knucklehead0202]

I don't have much time or patience really, so any engine swap for me had better be well worth it. A warmed-over factory engine just isn't enough when it comes to that honestly. If my box was a 3rd car and I had a shitload of spare time, i'd consider piddly little mods, but I want major whenever I do a lot of work. Go big or stay stock for my money. Everyone's situation is different though.

I like stock reliability. Seems stock stuff has a lot less chance of randomly eating itself than a fresh motor after assembly. Exploader does seem like the better way to go as those probably weren't beat on as hard as a VII or Rustang.

So it sounds like there is a chance that one could get away with a Mark VII PCM and an Explorer engine/intake/65mm throttle body & EGR spacer?

I'm in the same boat as the OP as I'm looking to drop a new engine into the '90 sometime this year if able. I have an early Explorer intake that I acquired from a local yard (very early, doesn't even have the boss for the throttle cable clip) and a Lightning EGR spacer and 65mm throttle body that David was nice enough to send to me in exchange for a few $s. Would this be workable with the speed density PCM and a stock HO cam? I've read that the primary consideration with speed density systems is camshaft selection. Closer lobe separation reduces manifold vacuum, making the MAP sensor useless, rendering the computer unable to compensate and run the engine correctly. I would love to run an aftermarket cam, but I want to avoid a snowball effect of supporting parts purchases.

Another consideration with this setup, stock HO cam or not, would it play nice with the stock AOD? Besides swapping the stock modulator, is there anything else (torque converter?) one might want to upgrade if dropping in a complete Explorer engine?

[DerekTheGreat]

oh yeh, I've got two early exploader uppers, 1 is part of a complete set that is painted and ready to go (By PO, I ended up not using it) I might be able to be convinced to ship them out.
