So....I don't believe that anyone makes a Nailhead manifold for IDF Webers? Kring and Inglese do for IDA but I'm not wanting a race engine; rather a perky cruiser with trumpets....hence the IDF preference. I can make the manifolds so that should not be a problem but I am interested to hear from anyone who might have done this already or can give me some advice on IDF size for my 364. IDF40? 44? 48? advanced thx... Pete
Be a cool setup I found This http://www.carburetion.com/Weber/wildv8.asp But I think your probably been all over it, I would just go for a size thats used for a similarly sized engine, or perhaps a little bigger. A few factors come into getting the exact size right, so no ones likely to have the correct formula for you It will be pricey though, but wow, they look nice Oh, there was someone asking the same question on the HAMB (kind of assume it was you)
