Should be a fairly simple swap overall.

You'll need to swap motor mounts. Then make sure ya have all the electronics for the new motor since the 4.6L ECU won't work, unless you go carb'd. Although if you go with EFI the explorer ECU uses the PATS system which can be a PITA. Oh and you'll have to make sure you get the proper exhaust, don't use the explorer exhaust manifolds cuz they use a y-pipe to single exhaust. Get the exhaust parts off of a Mustang so you can have full duals.

As for tranny I'm not sure if it bolts up or not, I believe that it does but could be wrong.

I'm sure there's lots of other little small things but thats probably most of the major things.

i'm talking about 5.0 explorer engine not 4.6

I think he got side-tracked a little.

The Explorer engine is a direct swap, for the most part. I believe you can use the stock 5.0 headers with the GT-40P heads on late 96+ Explorer 5.0's, but it's a really tight squeeze. You can also use the Explorer headers. The best thing to do is use GT-40P specific headers to maximize the performance gain. Another problem is the camshaft.

I don't know about the flywheel vs ring gear, and whether or not you'll need to drill anything out there. Also, the Exploder engine has no smog pump connections to the back of the heads. You'll probably need to mess around with the throttle body too. Since you have a 88 (I assume non California model) you'll also need to convert to a mass airflow setup because of the camshaft differences between the 5.0HO and the 5.0 Exploder GT-40P engine.

You'll also need to swap everything from the timing cover, forward. Including the balancer and the distributor. IMO its not really worth all the trouble.

thank you this was helpfull

Re: explorer 5.0 engine swap
 

Easily addressed by swapping in the 5.0 cam. The 85-88 SD cams are known to have faster ramps and better durations than the later cams. The only way to know exactly what you have is to take off the valve events and lobe centers/seperation. My 88 SD cam has 219*I/212.5* duration @ .050" lift with a 112.5 lsa (113*I/112*E lobe centers).

If you have to stay emissions, the Explorer intakes from the 96-early 97 Explorers have the internal EGR passages just like the stock intake,have the bosses in them for drilling/tapping the ACT and EGR coolant lines and will bolt right on. The later 97+ intakes do not have internal EGR passages or the ECT/EGR bosses.

Oh yeah. Oil pan and pump pick-up as well.

Re: explorer 5.0 engine swap
 

imo, id just use the the longblock, and go 5 ohhh all the way from there:) my heads and intake are explorer.

Re: explorer 5.0 engine swap
 

Sorry thought I read that you had a 1998 Stang, not a 88.

Re: explorer 5.0 engine swap
 

I would hope that with GT-40 heads you wouldn't be swapping in the HO cam. Technically, if you wanted to take the time and tune it, you could swap the cams, but it doesn't sound like that's his idea of fun.

The early 96's had smog pump passages in the heads because they didn't have GT-40P heads. They came equipped with GT-40 Irons.

Re: explorer 5.0 engine swap
 

The stock HO cam is better than the Explorer cam that's for sure. I'm at 277RWHP and 330RWTQ with mine at this stage.

If he doesn't want to swap cams, timing cover and the other things that need to be done, then he shouldn't even be thinking of doing this.

Re: explorer 5.0 engine swap
 

Good point, and also i might add, with a exploder cam, and stock valvesprings, he'll be pulling hard to a whopping 4k rpm :D vs the 5.0, or at least a cobra cam would pull alot further, especially with some roller rockers.
