When i figure it out, You'll be the first to know.
Hey all,

I have the chance on getting a low mileage 97 5.0L explorer motor, its got all GT40 parts, my plan was to buy this motor and do a rebuild on my 94 GT
using the best parts form both motors to make one good motor. I shouldn't have any major issues with this should I?

Any input is welcome :)

Thanks

No, and why rebuild a low milage engine? How low of milage is it? I have used these engines out of the truck and swap cam and timing set, put MAC P headers on the P headed ones, and swap throttle bodies and go with it. We had one on the dyno and with a stock cam it made 300 rwhp. NO CRAP. Of course it had long tube headers, cai, mass air, injectors, throttle body and spacer eliminator and a true cobra intake, but I about fell down when I saw it. He is on a board called StangBangerz.com based out of Cincinnati. His name is Kurt. He can tell you his setup better than I can. I just helped him tune it a little and ran the dyno. I was a believer after that.
Just swap cams and go with it. Is it for sure a GT40 engine, or is it the P heads? Either way they are both good. Kurt had the P motor, we've gotten more power out of the P than the std gt40's for some reason, think it's the smaller combustion chamber on the P's that helps it out more.

Hey,
My motor has around 120K on it, The Explorer has 89k, My block was rebuilt about 70K ago, I am not sure but I think my rear main is leaking, cause the old guy they owned and rebuild the motor, used olde gaskets and crap, I've already had to replace the intake gaskets, cause it was leaking oil. I did a search and that explorer motor was only listed as 210 HP, So I don't see how he got 300 RWH, I have an e-cam in my 94 GT, that will be pulled over to the new motor..I havn't decided what to do, all i do know is this motor is complete, and very cheap, I was thinking of pulling all the GT40 stuff off and installing it all my block. But if I can just install this motor in my car, I might just swap the cams, and my pullies, and my CAI, and see what happens?, will my 94 PC run this motor?.

Thanks

yes, the 94 pc will run the motor. I would definitely check if they are p or regular heads, since there were a few 97s that were early enough in production to have the regular heads. Also, you will need an elbow for the throttle body and from there its just plug and go.

Awesome, Well I am getting the motor, its way to good a deal to pass up, And it does have the GT40p heads on it :) So this is a great motor, swap my cam, and pullies, and my CAI, I should make some decent power, and with only 89K on it, theres lotsa of Ks in the bank :) I can get the elbow from somewhere, I can prob even find the headers as well :)

Thanks guys, been a huge help :)

forgot, check if the oil pan has the low oil sensor provision in it. I've never really looked at an explorer pan, and i'm sure they do, but the fox bodies didn't, so when i built my motor i had to pull my old pan off and reinstall it on the new one.

well, let me see. You seem to want hard proof. Well NMRA has a class called Factory Stock. You are only allowed P or GT40 heads, most run P's, no porting, stock cam, Cobra Or P intake, 70mm throttle body, flat top pistons, 1.7 rockers, stock K member, stock springs, drag radials, 80mm mass air, no lightweight items in the engine, like titanium or other trick materials, 5 speed, and they run mid to low 11's. Most make in the 350 to 360 rwhp range with that combo. Just because the factory rates it at something, doesn't mean with the proper surrounding mods, it won't make more power. That's like saying your stock engine only made 210, so that's all it will ever make. lol.
His car makes that power, I saw it, he is quite easy to talk to about his combo, he has a long block that is out of an explorer with 50k or lower milage, and put a cobra intake, stock cam, 1.7 rockers, and the other suporting mods I said. Try it and see, or just bury your head in the sand and say no it's not true, no it can't work, leave me alone! lol j/k.

No worries. It will make a lot more power with a tune and you won't need the 1.7's with that cam, it's got plenty of lift for those heads.
What intake are you gonna run? have you found out if it is gt40 or P's?

They are GT40Ps I am gonna run the GT40 instakes on it, with my e-cam, I heard it really wakes up this motor, I am installing underdrive pullies as well. So yeah it should wake the car up a bit LOL :)

Very nice man. I'll be doing a similar setup on the stock block. I want to run low 12's high 11's on slicks and still bust heads on the street. It's possible. Like Michael said, it's all in how you put it together and most importantly in the tune.

Too many people worried about numbers in my opinion.

Like my sig says...you don't live on a dyno. I have seen plenty of cars make less power than others and run faster.

Build it, have fun with it.

For me its about reliability, I don't want to be rebuilding my motor every 6 months, As for numbers, I would be happy with 300 to the crank. I love mt 5.0L, the sound it makes, the feeling of it, I love sitting at a light, hearing it idle :)

that guy I was telling you about runs solidly in the 11's with his coupe. He drives it around a lot, although it is a low milage, beautiful car. I think this is one of the best all around fun engine combos you can get without spending a ton of money. Post up some pics of the progress!

I sure will post some pics..Here are a couple he sent me of the motor, he gonna power wash it before I pick it up, and the clutch I bought to put on it. I have also decided to install a set of 24Lbs injectors and a MAF to match, then I'll do a tune to get the most out of her, I am thinking I should make 260-280 to the wheels, which is more then enough to have fun with. we are slso going to see a new place today with a garage, if we get it, I can start work on the stang right away, instead of having to wait for my bud to have a spot in his shop.

FYI- the MAF will not correct for the 24 lb injectors. You will have to run a cobra computer, or get a tune to correct the extra fuel.

the maf will correct it enough. while in there you could add an adjustable fuel pressure regulator to keep the fuel pressure up, make sure you get a gauge too if you do that. i ran my car with 24's fine with an adjusted maf and no afpr.
