Any body know who made this head back in the day ? I can't seem to find much about them would very much like to find one for my 6 cylinder
Knudsen made them. I have a Cyclone head that looks just like the Knudsen except for the logo. They are difficult to find an pricey when you find one. I have a Knudsen on my avatar and the cyclone is on a '49 project I'm working on.
Any flathead Ford six speed part seems to be pricey. Someone had a Cyclone head on Ebay for a long time with a price that matched "Rare" V8 flathead pairs.
There doesn't seem to be a whole lot of demand for 226 speed parts. I'm in the market, but absolutely not for the price folks are asking. Just cuz it's rare doesn't make it valuable! Haha Sent from my SM-G955U using The H.A.M.B. mobile app
I got to thinking about this 'cause I'm sitting on a low mileage stock Ford "H" flathead six motor and a nice 2 carb manifold setup. Not that I need yet another project at my age. But just thinkin.... Supposing you made a foundry pattern for each piece of a two piece aluminum head that would bolt together to enclose the cooling passages. It's been done before for flathead V-8's. That's a two plus foot long piece of fine wood work. Lots of hours there. But suppose we 3d print each of the one cylinder sections and caps for each end; 8+2 end pieces pieces that fasten together for the combustion chamber below and another such for the top of the head and all the fins. Cad drawings are a lot less work than carving wood. And besides, if you have a 3d printer that can do an entire head pattern you probably won't be playing in my league, you'll probably be too busy getting your ride ready for some event with a fancy name. Same approach may work for 4 bangers. And inline manifolds. The real fun comes with finding a foundry to cast aluminum 356. Were you to spend a year of more constructing a wood pattern the idea of sending it halfway around the world to a foundry in some third world country may be scary. But note you will have a lot less tied up in 3d prints. Just remember that 3d prints can have some roughness from the successive layers of plastic on curved surfaces. This has to be polished out for a sand foundry pattern so the 3d printing material has to be OK for that kind of finish work. Some tough plastics are not easy to polish. Not my idea of fun. Now I'm gonna get real crazy. Are there any little inline flathead 4 banger engines out there that are in good supply and have never been considered for street rod applications? Could be a new craze building here. Consider how far cycle carts have come since someone just happened to notice a particular size of motorcycle wheel and tire that was "just right". And gas isn't getting any cheaper. ............... DF
Years ago at Pleasanton I ran into a guy who’s name was Kevin, I think he was on the Hamb and went by cyclonekevin here on the hamb. He had something to do with the old cyclone speed equipment. At the time I was building my single seater and using a dodge 230 flathead six. I asked about a head and he said if I could make a pattern he could cast it. At least that’s what I remember I don’t know if he was pulling my leg or not.
Any foundry will tell you the same. Then, got to find a machine shop to make the raw casting into a usable part. Over on the Hudson forum, a friend of mine just finished a years-long project for an aluminum head. The net was $1500 each, minimum fifty units, cash in advance. If you've got $75,000 to invest, you could have your heads in a couple of years. jack vines
