    Yes, Offenhauser rules.

    Well, i dunno, kind of high revving. Its a single plane intake. Id say its along the lines of an edelbrock torker 2 which is good for beween 2500 and 6500 rpm. Kinda high to me.

    Single plane is for high(er) rpms. 400 sbs do not like high rpms unless built for it. It would also need to match other components that work in the same rpm range.

    The question is pretty broad, is that intake good for 400 cu. in.
    Um Yes No Maybe.
    Is that a stock 400?
    It really depends on everything else. You gave no specs.
    What compression, cam, heads, and what rpms you're after either low end grunt or screamin top end.
    Match the intake to the rest of the engine and what you're after.

    I'll be gathering parts for the build up in the near future. End usage will be mostly trails in the forest (Light rocks, nothing major), mudding, and a daily driver. I personally stay away from anything with the word Edelbrock printed on it. So was hoping this Offy intake would work for me sence I can get it pretty cheap.

    Well I think that would work great for the supercharger your putting on it. And it even has the right bolt pattern for the Vortec heads your going to bolt on and .515 cam going into it. /forums/images/graemlins/rolleyes.gif
    Could I make one minor suggestion? Be more vague. /forums/images/graemlins/rotfl.gif I'm going to regret this I know but what is it you have against 'ol uncle Vic?

    [/ QUOTE ] I don't belive the quality controle is what it used to be, and I like to be different. Everybody and thier brother has a Edelbrock intake. I've always gone with the Dart 2 intake manifold on the hot rods, but it's power range is 1500 to 6500 rpm. I didn't notice this one is a single plane. Should have looked better. No parts bought yet, still planning it. I've gotta get my tires and rims bought first and get the 3/4 axles under the K5 befor I start buying motor parts.

    This may be a dumb question (probably is), but if it's a single plane intake, what is the center divider for? (Splitting left and right banks)?
    Most single plane intakes I have seen Edlebrock, Victor Bowtie, etc. all have a solid opening underneath the carb (great for high RPMS), or is the center divider there to help lower the effective RPM range of the single plane.....sorry just my curios mind at work.

    If you want to be "different" then get a Weiand Action Plus #8000/8004/8024(depending on your heads). Pretty much equal to the Performer but not an Edelbrock. /forums/images/graemlins/thumb.gif

    For Wieand, I'm still consittering the "Stealth" intake manifold. It's been a long time sence I've seen anyone running a Offenhauser intake manifold. You see Edelbrock's on everything, I kinda want a Offy., but a Wieand is my next choice.

    and there is a reason you see edlebrocks on alot of stuff:

    good manifolds at good prices.

    Looks like a dual to me also, thats why I was wondering why everyone was saying it wasnt. All the runners look like they are the same hight like a single but maybe thats an illusion??? I aint an expert either, all I know is enough to /forums/images/graemlins/ignore.gif stuff up /forums/images/graemlins/crazy.gif

    I really dont think you will notice much if any difference even on a dyno between 2 similar manifolds between 2 different manufacturers. Bt thats just me, go with what ever is cheapest as long as its got nice workmanship and its the basic design you need IMO.

    I was wondering the same thing. The runners are laid out (from external apperance) in a single plane fashion, yet it has the divider that is the hallmark of the dual plane....

    I had a Holley intake a while back that had the center divider. I thought it was a dual plane because of that. However I was told it was a single plain. Most single planes I've seen are wide open like mentioned above.

    But someone told me it's not the center divider, it's the layout of the runners. Dual plane runners cross over from, for example, the left side of the carb to the right side of the motor and vice versa. A single plain just has runners that go from the left side of the carb to the left bank of the motor. That's how I understand it now. But that doesn't mean that what I just said is actually true.

    [/ QUOTE ] Advertisment and mass distrubutation is no replacement for quality controle. Compare one of thier intake manifolds made 20 years ago to one made today. When I spend my money on a intake, it's going to be either a Offy, Wieand, or a Dart.

    I fixed it for you. /forums/images/graemlins/smirk.gif

    I got a performer on mine and it kicks arse.
