can anyone ID this intake... similar to GT-40

[BelueLX]

Can anyone ID this intake manifold by the number on it. I was under the impression it was a GT40-Cobra lower. The person who bought it is saying it is not and their boxed truck upper will not bolt up to it. Thanks for any info.

Number on it: XRF-E6SE-9K46(1?)-BA

Thanks.

could be a gt40, cobra, or explorer lower. not sure how to tell the difference. either way why did the person with the truck even buy it if he did not have a matching upper?

E-mail I received:

The Lower intake manifold you sold her is not a GT-40. It is slightly different the difference is enough that the bolt/stud holes that mount the upper to the lower do not line up. I had Tommie Vaughn here in Houston confirm this. The upper intake manifold she bought is a Cartech/Downs GT-40 Box intake that bolted up fine to the display model lower at Tommie Vaughn Ford. This is the same intake I am using on my 408W Stroker with a GT-40 351w lower. To show you what intake I am talking about copy and paste this link.

based on what i have heard and read, all the gt40 style lowers are the same, with the exception of one outflowing another slightly, cant remember which one. not sure on this one, hopefully someone on here knows a little bit more about that upper.

i would lose money on a bet it that wasnt a gt40,it even has a place for the sensor between number 5 and 6 cyl.i think it is a gt40 off of an explorer possibly

anyone know for sure what it is from. thanks for the replys.

i would think where its from would be irrelevant, but someone should be able to help you out with that. maybe the box style needs a different lower. to my understanding all the gt40 style upper and lowers are interchangable as far as the bolt holes.

that is a gt-40 lower intake but i cant tell you if it is an explorer, a cobra, or a fms intake. looks like an early explorer intake which is the same as the gt-40. but..... the truck box intake is totally different. the bolt pattern is the same as an edelbrock. somebody will correct me if i am wrong.

Take a look at the part numbers.


E6SE

That's a 1986 part number.

As far as i know, the GT-40 intake did not exist in '86.

It's possible that's an early Marine engine lower intake manifold.

It does look similar to a true Cobra lower though

it doesnt matter. the prob at hand to me is... he is trying to mate a gt-40 style lower to a truck upper. that is the old apples to oranges cliche or the square peg in a round hole. it just wont work. if i understand correctly?

I can't tell you what exact vehicle it came off of but I can tell you that whatever it was had either an 86 H.O. motor or 86-91 S.O. motor.

Probably doesn't help much but I don't know what specific vehicles used those intake aside from the Explorers and Mustangs. I don't recall there being any Mustangs in 86 using a GT-40 intake unless the Saleens did. That leaves Thunderbirds, Crown Vics, and the Lincoln Mark VII. If it's a Thunderbird or Crown Vic, they DID use a different upper plenum from the H.O. motors and that would explain the bolt pattern difference (if there is one).

H.O. motors around that time would have been Mustang, Lincoln, and Explorer?

S.O. motors were Thunderbird and Crown Vic? (if that's correct it would mean different upper intakes and probably slightly different lower)

Maybe somone else will come along with another piece of the puzzle.

it wont work.. 5L5 is right.. 86 part number.. i have the same one in my garage as just a spare i believe..

You posted while I was... given that info, it's got to be from a Lincoln or explorer. They used the high swirl 86 blocks (heads) for a number of years after 86 even though they were only used In Mustangs for one year.

 

[troyGT03]

there was no explorer in 86... the explorer didnt come with the 5.0 until 96 with the 5.0(thinking). i am not sure the 86 casting # means 1986. the gt-40 aftermarket intake from fms didnt come until about 88 if i remember correctly. the saleen/vortech intake had the truck bolt pattern and not the gt-40 pattern. correct me if i am wrong.

 

[troyGT03]

the saleen intake came about in 89 if i remember

 

[Thenemesis]

that is infact a 86 (numbered anyway) part.. E in the number equals 80's.. f means 90's part and X means 00-10 i believe.. thanks to dad i can figure out a part down to what it is.. lol

 

[Daggar]

Well the casting number is definitely 86 so that leaves the Lincoln Mark VII. It's the only other H.O. aside from the Mustang that was 86+ if there was no Bronco. Since it's an E6SE casting, it had to come off of a motor that used the 86 Roller block/heads. If I remember right (and I'm not certain that I do) the S.O. motors used intakes that resembled the 86 Mustang stock lower (inline ports) and not one that looks like the GT-40.

the lincoln used thed the same mustang inline port intake but was turned 180 degrees so the upper was positioned to the drivers side, it was the same for the crown vic , mustang, etc. the casting # needs to be checked again. that intake didnt exist in 86. not until 89 if i remember.

Ok... but if the part number is correct, it still has to come from a car that used an 86 style H.O. roller block with swirl port heads. So which vehicles were they? If the GT-40 intake didn't come around until 88 then it's a vehicle that had the 86 roller block after the 88 (assuming that the intake we're looking at is a GT-40 and not a predecessor). What about the Broncos?

 

[1EVIL88VERT]

Is it just me or does that intake not have a hole for PCV? I thought they all had one at the back ( cobra,exploder,gt40 )?
