    I was looking through the inline6 intake posts and was wondering does anybody have pics of a dual intake made from the stock cast single? If I missed a post on it direct me to the link.
    My interest lies in the 216 chevy.
    I know it's been done, let's see what it looks like.

    I've seen it done with 223 inline fords. In my opinion it looks like a hack job. Maybe because it was. I think a guy would be better off building one from scratch.

    I recall that Offy sold carb mounting pads that you could weld onto your manifold. I think they are still in their catalog.
     
  4. there's a guy named George Asche that does them for Mopar flathead sixes. I bet if you search his name you'll find a pic.

    Here are some dual and triple homemade intakes that I have found. To me they do look like a hack job. I would also bet that they wouldn't run as good as a properly built intake. I mean why not pay for a nice vintage or reproduction intake that someone has taken the time and money to build something that's just for your particular engine? Actually the second picture may run good and looks different. But those triples, I don't know.

    Thanks for the replies.
    I don't think they look bad at all. I was just wondering what would have been done before aftermarket intakes came on the market.
    I might have to see if I can screw up a couple of intakes...:D

    I think those look great, as far as working well? Have you ever had a 3-2 set up on a SBC they don't work for **** either but they look good! If the Hot rodders in 1935 didn't ever try anything cool where would we be now? All 1 pot manifolds, Build em yourself!

    Kinda what I was thinking. Not to mention that everything functional has to be pretty or aluminum.......:D

    When these motors were raced in the 40’s and 50’s the intakes were all homemade. The guys that ran the cast aluminum intakes were the guys that were making them! Yes some do look like hack jobs, most were acetylene welded or stick welded. A homemade intake will work fine. Try to copy a design that has been proven to work. I have seen plenty log type manifolds on inlines. I’m working on adding two Holley 94’s to a stock 235 intake. I took a piece of pipe, split it down the middle and spread it apart like a “ V “ then I filled in the gap with sheet metal I still need to weld the base plate to the top. The only thing that kind of makes it look funny is the large square heat chamber for the middle carb (this part gets capped because its not being used). The other thing is the stock intake needs to be nickel welded because it is cast iron. I use my stick welder. Some have mig welded them with good results. The intake is not like the exhaust so you wont have much movement. This makes your chances of the weld cracking less if you decide to mig weld(as long as it was welded with proper heat up and cool down). Oh and ping the weld as you go!

    Heres the one we just made. Using the gl*** bowl holley carbs and everything is homemade.
    I dont understand some of the other replys.
    I feel as if "hot rodding" is gettin it done by making and using everything you got. Thats the way it was in the day. We couldnt afford those intakes and manifolds from honest charlie etc.
    Ever wonder why there are so many of those old units nos (new old stock) ?? Thats because the speed shops were full of them.:)
    A machine shop behind our shop milled and made this one for $20 bucks..:eek:

    I recall that a guy from Clarkston named Mike Mraz (his family owned a machine shop, I believe) ran a 40 Chev coupe with a 302 GMC - he made his own 5 carb intake, and split exhaust manifolds. He ran it up at Deer Park Drags in Spokane...this was back in late 50s, early 60s. It was a beautiful engine, he did excellent work.
