Guys,

I'm planning my 5.0 build and ran across a couple of threads regarding the Explorer/Mustang intake. I know that this unit flows better than a truck unit but what (if any), is the downside to this install? Do the throttle and cruise cables just bolt up? Is there a difference in the injection system? Is it taller or shorter? Any help would be appreciated.

Never worked on a 5.0, but from what I remember, you'll need to adapt the throttle cable/assembly and cruise control to fit onto the assembly. I also believe I remember reading that you'll loose some low end torque since the truck intake has longer, skinny intake runners which help at low rpm, but are what limits the flow at higher RPM.

Hopefully somebody with better knowledge of the 5.0 will chime in too.

 

Its the gt40 intake which is pretty much a 5.0 HO intake im by a JY now that have like 8 of them

 

Ive seen them used but depending on the hp requirements the stock intake will do fine

 

as for the stang intake you're gonna have to remount your air cleaner assembly as the throttlebody is on the opposite side. As well setting your TPS voltage is harder on the stang intake cause it's on the bottom of the throttlebody unlike the truck which is at the top. When I built my 5.0 HO I used the truck intake

 

I guess you could use a intake off a HO 5.0, but the GT40 style manifolds(Explorers and Cobras) are the ones most people use if they don't retain the truck manifold.

 

I would keep the truck intake , its very good ,,,,Lew

 

Not unless you get a late model(94+)car intake with the integrated elbow like the one shown below, this one can only be oriented with the TB on the passenger side but on earlier versions the upper can be flipped 180 degrees.




Double No, compare the GT40 and Explorer uppers below to the HO pictured above.




Can't believe everything you read.

The truck intake is by far the largest and best flowing stock 5.0 intake Ford ever produced. I recently learned that it flows close to 200cfm per runner untouched and will do close to 250cfm with a little port matching on the lower exits. In comparison the HO and GT40 intakes only manage about 125-150cfm as delivered, and while the GT40 can deliver close to 200cfm/runner it takes extensive porting to get there. Here are all 3 lowers side by side with the HO on the left, truck in the middle, and GT40/Explorer on the right. As you can see all 3 intakes are totally different designs which means the parts are not interchangable.


Total runner length of these three intakes is also pretty close.. there's only 1-2" difference between them so their tuning is similar.

As for what intake is best suited for any application, the HO is the best choice for a 5.0 motor with stock heads, it's smaller runners will build more air velocity at lower rpms and that will make more TQ. The GT40 is the best choice for a 5.0 with upgraded heads and more cam, the runners are small enough to maintain good low rpm performance but big enough to allow the engine to breath better. The truck intake is really no good for anything smaller than a 347 stroker truck motor, I say a truck motor because the long runners become a restriction at higher rpms(5k+) so it's not a good choice for an engine that will see lots of rpms.

 

As always Conanski Great Info !

 

I should just stick to the 460's. At least I've wrenched on one of those. Thanks for clearing things up.

 

ive seen some of the mark VIIs i believe ill take a pic of one next time im at the scrap yard they dont have the built in elbow on them.

 

The only thing i can say is that the truck intake , on a modified motor makes more TQ , and at a lower rpm than the mustang intake , less HP , but more TQ , i have seen the dyno results on both , the mustang intake makes its TQ at a higher rpm when the truck intake makes it at 2000 up to 5500 , thats on the dyno & shows the same results at the track , so its about 10hp less , but about 20 more ft lbs on total TQ,,,, so at 3000 rpm my truck is pulling alot more than the mustang will with the same motor , thats been my experiance having had both , & just my opinion....Lew

 

Only the '94-'95 mustangs had the elbow, as far as I know.

 

i have done the swap with a mustang HO intake

the throttle cable and cruise control will both work if you get the throttle/ cruise bracket off off of the mustang
the cables are also long enough if you want to keep the intake facing the correct direction it was meant too (towards the passenger side)

the wiring harness will need to be modified a little bit to have all the wires reach there appropriate plugs

i would recommend that you flip the intake and have it face the drivers side
i think that it looks better facing this way in the engine bay and you can use the factory box (MAF box that is) and a 93-95 lightning intake tube. easiest way to get the intake piping done in my opinion at least.

heres a couple of mine before i flipped it around

Thunderbirds had the elbow as well before they went modular. Lincoln's Mark car went modular before the elbow came out.

Doesn't really change anything, just thought I'd share haha.
