    Default Factory 4v intake = Holley contender

    Read many times the factory intake was a Performer which always seem wrong to me ... but couldn't find a pic to illustrate until now ...

    Holley Contender :

    the factory intake is neither a holley performer or holley contender, they are very similar to the eye but not the same.

    There are differences in looks. But performance, as stated, it's basically the same. May get you a couple HP more and the Edelbrock name. but nothing like a Stealth.

    You can tell the intake passages aren't the same size. The factory passages are smaller.

    It's not that much different...

    the plenum and runners to cylinder 1 are a bit different.

    Tony, A FEP member here, had ported my factory intake. He said the runners were run a little be better than the factory one. And, we all know the factory ports are smaller. The runners on the Edelbrock don't have as sharp as a turn than the factory one.

    You are making that observation from the outside without knowing the internal wall thickness.

    The truth is there is very little performance advantage over the stock manifold.

    The Stealth won't pass smog here in Cali, no EGR provision.

    I didn't exactly say "inner cross-section" of the intake passage. I was clearly referring to the casting as seen from the outside. If they were the same, the casting would be the same, except one would have the Holley logo and the other would not.

    Contender and factory are not the same casting, that's clear, but if you look close, there are too many similarities to deny they aren't related ... overall shape of runners, cylinder numbers on runners, holes for accelerator cable bracket, etc ... way more similarities than Performer vs factory.

    Remember that in those days, Ford asked Holley to design the 4180 ... won't be surprising that Holley also designed the intake using some of their own casting as a template as they did for the 4180C with the 4160.

    The basic runner design of the performer is still very much alike. The runners take the
    same path as the other two with very little changes. The divided plenum and the basic
    castings are the main difference. They are functionally similar designs.

    I remember reading Ford gave Edelbrock some guff about copying their intake design
    so maybe that is the reason for the slightly different casting design.

    Sorry guys, I just realized I'm saying the Performer 289 is the same design.

    The Performer 302 is clearly a third variation design (with similar runners)



    Bottom line these are all variations of the same 180 degree dual plane.

    If your car runs clean and hasn't had too many mods then yes. The problem in Cali is not the sniffer test for the most part, it is the visual inspection. The way Californian bureaucrats see it is if it passes smog without the parts on the car, think how much cleaner it would run with the smog stuff on there!!!

    It's a no win situation here. If you have someone that will over look the mods and they will still pass it, I say go for it but keep in mind that down the road your buddy might not always be in business and then what?

    Geeze, there goes another one. And this from someone in Houston of all places. Sorry BW,
    but I've been to Houston once or twice...

    California smog checks aren't nearly as difficult as you guys want to make it out to be, you
    just have to know the rules. And it's only every other year. I can think of a lot of things that
    bother me about what outsiders have done to California, but smog checks are way down the
    list.

    Seeing some guys complain about their inspections to get a sticker come to mind. OMG the dome light doesn't work.

    I preach what JACook is saying on my other forum. Know the rules and what you can get a way with and you can have a fast car/truck.

    Kinda cool how a design dating back to 1965 remains relevant?
