It will fit, but you are wasting money by putting it in.

The 390 fe motor was JUNK where performance is concerned. You'd do much better to take that 390 to a salvage yard and trade them for a 351w to build.

There are TONS of mustangs running around with 351w's in them, and there is a plethora of performance parts available for the 351w swap, but I will garuntee you there are NONE for the 390 swap.

You'd have to fabricate EVERYTHING to do it. (Or pay someone else to!)

Do yourself a favor and go with the windsor. You'll be alot happier!

I looked into it about a year ago, its not worth it. Those motors dont have many parts avialable, and if they do they are very expensive. Not to mention that they weigh a TON!

It would be expensive but can't you make a 428 out of a 390? That would not only be unique but ol 428 mustangs hauled. Really I remeber a 68 GT with a 390 and 4 speed in town that really went. Personally a 460 or 351 conversion is more common and swap parts are plenty but if you can fabricate your own stuff it would be fun to do a swap like that over a winter.

I've heard that a oil pan for a 4wd truck could be used to swap an FE engine in a fox body but unfortunately, even if it did work, no one makes the headers or engine mounts for it. Engine mounts wouldn't be that big a deal to make work but the headers are a different story. Besides, a 428 would be a MUCH better choice if it this type of swap were practical.

Actually,Hedman Hedders make FE into a Fox headers,these are full length headers.

I always thought the oilpan would be a pain,but if a 4WD truck pan fits(a van pan might fit),and Headman stocks the headers.Run an engine plate or weld some diamond plate steel to the frame and use the FE mounts.

I do know a 428 crank inti a 360/390 will make a 410,assuming stock bores.

I wouldn't call a 390 junk

they have potential. It's just expensive to make anything out of one. Most were under 200hp stock. There were a few exceptions (335 hp I think?)-4 speed Fairlane? I do not remember.

I think they can be bored/stroked to 446" and that is about the max. With GOOD heads and forced induction, I would imagine 1000hp wouldn't be out of the question, IF you can keep it together. Most FE blocks are not known for strength.

Craft Performance in Arkansas has done a bunch of them. Again it takes money. Lots of it. Probably more of it than it takes to build a decent Mopar RB engine which isn't cheap either. Especially now.

One thing about a well built FE, is that they have a sound all their own. There is no mistaking one. Probably one of the better sounding old school V8's ever in my opinion.
