Ok I was browsing another board and saw that the website someone referred someone else to for parts was offering engines so I said hey what the heck I'll give them a call. Turns out they have a 20,000 mile 1997 Ford Explorer Engine with the GT-40 Heads

He is asking 750.00 for the long block - I didn't get to detailed but you get the idea... If I buy it I plan on getting a new cam.

But before all that...We are dealing with a 1986 GT here and we are slapping a Explorer engine in the compartment thats like 16 years newer than my engine is. Do any of you know of any major modifications that I will have to make in order for this thing to run right? For example electronic issues between computer and engine...a different wiring setup?
If I have to make major mods Ill just buy a reman'd one for 1350, one thats designed for my car.

Post what you know so I can get this guy an answer.

 

i'd go with the Gt-40 motor. your car is speed density though. so you can convert it to mass air, or go carbed. either way that speed density i hear is real hard to mod so you are going to end up doing one or the other down the road anyway.

 

the only snag your catch after you swap the motors and swtich to maf is this.

your new engine does not have anywhere to plug a air intake charge sensor. To my understanding is the computer doesnt really care what the temp is, just that there is a temperature. On big b's car we just plugged one in and ziptied it to the fuel rail (explorer lower intake on a 91) . Other than that its pretty straight forward. i would strongly reccomend swithing to MAF over speed density, PM helmut roner, he can point you in the right direction.

In 1997 the Explorer started using GT-40"P" heads. The spark plug was repositioned more towards the center of the combustion chamber for better mixture burn. You would need a set of "P" specific headers.

You can put heads & intake on a speed density car. Cams are where you have to be careful. There are cams that can also work with speed density, but you can't go past a certain amount of duration and lobe angle separation (I can't remember specific numbers at the moment).

It doesn't matter how much newer the motor is compared to your car. You would only have to swap your timing chain cover, water pump, oil pan, oil screen, balancer, whatever other Foxbody brackets you have in your car, distributor, and your flywheel or flexplate to the newer motor.

Assuming the newer motor has the throttle body intake tract you will have to remove that to take the spacer/elbow off. All your existing wiring will hook right up after having swapped the motor into the car.

For mass air conversion do a search on all the different Mustang sites because that topic has been beaten to death so many millions of times.

After you're done with the swap you have to sign the title to your 86 GT over to me free of charge.

 

i need to stop taking for granted that not everyone know as much as i do about mustangs.

 

btw, new headlight would make the front of that car BLING!!

 

wouldnt a newer wiring harness fix this problem as well????
