    Thanks for posting this! Ich habe es jetzt gekauft. (I bought it now).
    Faced with finding a tii booster, this seems like a slick solution. We'll see how it goes.
    Thanks again - great find.

    Ha ha. Truth be told, I tend to be a bit of a parts hoarder myself. Give me a bit more time and I hope to build my own hoard (much to my wife's dismay). In this case, I think this manifold will find a good home on the Raven.

    I have same on my engine. Will also allow you to run longer trumpets and foam sock filters if you choose. Good price too.

    Oh yes, that is beautiful! I'm excited.
    Say, did you fit the foam filter socks over the trumpets? (actual question: are there trumpets under the socks?)

    I don't think so. If you look at Steve's picture, the throats of the carburetors are not evenly spaced. The manifold that Alpina used (and the Korman intake that I have) evenly space the carburetors from one another. This is why they require a different tstat housing.

    I have a Korman intake manifold (manifold only) I would sell-have to dig it out of the garage, lol.

    Wait, what? :( I hadn't noticed the variance in spacing from side to side. The benefit I see in this manifold is that they raise the carbs up to clear the brake booster. I did notice that the manifold also seemed to shift the lateral position of the carbs, but hadn't noticed it was not consistent. I wonder why this was done this way.

    I still think it will solve the brake booster clearance. I was planning on using glorious trumpets and celebrating that look - still probably will. But a second options is that I could custom fabricate an air intake that would provide better filtration blur the spacing. I'll learn more once this piece arrives and I noodle with it.

    As Ohmess said, it will not fit an Alpina airbox. The spacing is not even because of the thermostat clearance. The carbs will be raised and slanted upward slightly (as Weber said should be done) so you will definitely be able to clear the booster with trumpets. There is a matching VGS airbox for these, I almost bought one when it came up but I am not planning on using an airbox because I don't want any sound muffled. Plus it is designed to fit over the thinner 2800 booster. So using the trumpets I linked to plus sock filters works just fine for me.

    The Alpina manifolds have studs in them that line up with, and secure the Alpina air box.

    Hey Steve -- I know we've been through this, but my guess is the others in this thread will have the same question. In looking at the pictures of the intake on ebay, there appears to be a vacuum opening in 2 and 5. The Korman intake also has openings in 2 and 5, but they are underneath the manifold rather than on top. I combined these and use the vacuum for both brake booster and as an input to my 123 distributor. You appear to be using only the number 1 cylinder for vacuum and are using it only for the brake booster; do I have that right?

    #2 and 5 are holes for a linkage crossbar if so fitted. I use the intercouple linkage so I have those capped-a big assed stainless bolt can be seen on #5 in my pic. I suppose they could also be used for vacuum but the holes are pretty big and you'd have to fabricate some sort of threaded take-off port. Yes I am only using #1 for booster, currently not using any vac advance on the 123.

    I don't think you need to change the brake booster if you use the Alpina set up, that is what I have been told, and want to believe
