Found this article on that "other" site.

swapping on a polished intake? am i missing something here. what are you gonna gain from that?
i dont see any photos of the actual " porting " performed. unless the jug was cut off the bottom of the intake, and the runner tubes were fully ported 100 % top to bottom, then welded back together, the only thing you could possible port on a gen 1 intake as you see it, are the throttle body bores and the ends of the tubes where the intake bolts to the heads, which would be absolutely pointless. unless you cut one of them in half and port it fully and tig weld it back together i wouldnt bother going anywhere near the gen 1 intake with any porting tools.
 
Nothing but a polished intake. Guess this is when inside beauty is suppose to count. :)
 
I still have a pretty much complete 96' engine on a stand in my garage. A friend of mine was trying to get me to throw that intake on my 98' to see if it gave me a performance gain but I think I'm gonna hold out gor a Cobra intake instead :confused:

WOW:eek: A 96 foot long engine??? That's impressive! **just kidding**;)

Personally, I like the looks of the GEN1 intakes. I would put one on my '97 if I thought they would provide any hp boost at all. The "bundle of snakes" design just looks cool as heck as opposed to the rather generic look of the GWN2 intakes.

i bet there is a horsepower increase. cobra intake swapped gen 1s don't see the increase gen 2s do.
but for all the work involved swapping things around, go for the cobra intake.
 
Wow, that was digging in the archives. :)

Pretty much describes the intake I have. More 'polished' than 'ported' and then it was jet coated baby smooth and shiny on the inside same as the outside.

The intake could be ported by extrude honing without having to cut or weld anything.

The tubes on the Gen1 intake are too thin for extrude honing. I forget the actual wall thickness but they are quite thin-walled. That and a custom manifold jig would be required which would place the price into the stratosphere. I've often wondered if anyone has extrude honed a '96-'98 Cobra intake? I searched long and hard before and never did find any success. They are more of a cast tube and have much thicker wall material to work with.

Most of the gains on the Gen1 modified intake I believe are had from radiusing the inlet for each tube inside the plenum. The proper radius is around 3/32nds of an inch for optimum diameter to diameter ratio if I recall correctly.
 
i took the time and energy to polish the ports on a gen 1 intake. like Jamie said cutting the bottom then using long spindles and a lot of cussing later got it done rewelded the bottom then mike(94m5) let it go somewhere. trade or scrap don,t know. extrude honing would be my choice if i wanted to do it again. as John ( Driller) said changing the radius doesn,t take that much. while doing the polishing also match the ports the gaskets fit the heads fine but the manifold is a different story.
 
Has anyone ever extrude honed an intake? When I worked in hydraulic valves we did massive amounts of honning on lots of different equipment. We shied away from extrude honing for a variety of reasons. One being, as Diller mentions, every item you hone needs a dedicated fixture. It would do a relatively good job at deburring, and blending sharp corners. It would never do a good job at targeted controlled material removal which is what you need when porting. besides, it is not really honing where you pricecly control the metal removal. More like liquid sand blasting under pressure. Plus, you would need a stack of intakes to nail down the process. I could be wrong, but I would be interested to see if anyone has done a 1-off extrude job on a manifold.

No, wasn't digging at all, just searched some things on google like "Mark VIII intake" and it gives me all sorts of goodies lol. Hmm, I shall remember this 3/32nds of an inch for future reference. Then again, when income tax comes, I may swap 96-98 cobra intake, or just go with a c-head swap! :D

The Gen1 intake is way better than the Gen2 intake. I scrapped my stock Gen2 intake at the yard. I couldn't even sell it LOL

I've heard of extrude honed Cobra 5.0L intakes. I'm not sure what this one is...

Hmm, So Which Would Net The Best Gains For A Gen 1?

Installing A 96-98 Cobra Intake, Port N Polish.

C Head Swap With 99/01 Cobra Intake, Port N Polish 01 Intake, Extrude Hone 99 Intake For The "Fix" If It Hasn't Been Done, And Then Port N Polish.

C Head Swap With 03/04 Mach 1 Intake, Port N Polish <<Heard This Intake Was The Best.

I Know The C Head Swap Will Cost More With Extra Equipment Required, But Would It Be Worth It?

C Head Swap I Heard Is Harder On A Gen 1 I Read Somewhere, This True?

Sorry For Typing Each Word With A Capital Letter At The Beginning, I Think It Looks Better Sometimes. :D I'll stop now.

I just like the look of 99/01 intakes with the cobra emblem, and plus the c heads have more intake alternatives, and come with more horsepower out of the box, also have a better valvetrain, then 93-95 Marks.
 
C-Head swap (which requires new manifolds and some exhaust work). Most expensive route I guess, but opens the door to more upgrades. However, the Cobra and Mach intake manifolds are the same, less the snake logo. I had both and only put the Mach intake in for bragging rights and I got it cheap. Already had the Cobra intake for a while.

And a Cobra intake on a Gen One does not much in the way of gains, if any. On a Gen two, thats a different story.

In either case you will be re-working the engine harness since on a Gen one is crosses right over the intake.

Since a whole low milage Aviator engine, with c-head, can be had for less than $1500 you may want to consider just swapping the whole dang thing. You can sell the Aviator intake for the price of a Mach/Cobra intake. Or if you are daring, use the Aviator intake. Gonna have hood clearance issues though!

I never heard that and wouldn't know why.

I think it depends on your goals... with a SC the B-heads are fine with better valve springs. Most go with C heads because of intake preferences.

Dang it kid...

So ya. Pretty easy swap. If you wish to just do the heads you will need exhaust manifolds too.

• Intake manifold (99+ Cobra or 03+ Mach)
• Cobra or Mach throttle body. Not sure if a Gen II TB will work
• Cobra throttle cable (your stock cruise will probably work, it did for me)
• EGR tube (if your into that sorta thing)
• Exhaust manifolds
• 03/04 heads would be best, either Cobra or Aviator

The Cobra intake cams are best but Aviator exhaust cams are the best. Odds are Aviator heads will be cheaper. If you feel up to it, you could then swap in some Cobra intake cams and get the best stock-part setup.

You will need some custom exhaust work to mate up to the cat-less driver-side manifold. You will need to modify the steering in a way to clear the exhaust manifolds. Pretty straight forward, a few have done it just to upgrade manifolds.

Your stock engine harness will probably work but may need some very minor extension of sensor wires. Overall it should not be a problem unlike a Gen 1.

You will need a tune to kill the IMRC, AIR trigger for the CE.

:D Well I guess I misread it, you where just talking about the engine harness lol. I guess it all depends, if I have the money or not to do such things. We will see how things turn out, hopefully they turn out good! :D Really want the C-Heads though.

Heard the Aviator intake is the crappiest, so no one would most likely be interested. Maybe Ebay or some Mustang forums will be my best bet, or see if any local or close junkyards have 99+ continental heads.

Crappiest intake? I guess if you consider a massive intake with IMRCs for good low end and high end power as well as attentional torque, then yes its the crappiest. Also I wonder why hot rod builders kill for em.

Just saying ya need to be careful what ya read! :)
 
Another option, is to source a 99 continental engine. Then you could use the heads and adapter plates with your stock gen 1 intake manifold. It would look stealthy. You could find 03/04 cobra or mach1 manifolds for cheap. You could prolly get the stock catalytic H pipe for cheap. I got 03 mach1 manifolds and egr pipe/valve for $20. Also got a 03 mach 1 stock H pipe for $150.
Since the stock continental intake manifold is cast, you could also trial fit that. IF it works you could have that extrude honed.

From low end torque , less then 3000, it says the Aviator intake held the edge. Above 3, the Cobra had very good power gains. Yes, it's good for low end torque because of IMRC's , but still with porting and polishing and reworking it, and having to get a new hood, it's better to port a Cobra Intake and maybe shorten it, when all said and done. Have read alot lately on the two intakes, and everyone seems to stay away from the Aviator, but I will keep reading. Maybe, I will just buy this one instead. :p
