If you are interested in a set of Roof 16 Valve Competition Exhaust manifolds I am having some cast. The patterns are being made right now. The final figures are not in yet but I'm expecting them to be less than $600 a pair. The total cost will be divided up by the number ordered and shipping. When we get closer to production I will have a more exact cost figure. At that time I will want 50% down before the order is placed. No Money No Order. The foundry and pattern maker have been in business many years and are competent. Because this is a not for profit venture I will not be responsible for the end product. I am not expecting any problems, but I am not going to be the warranty company. I don't have machining cost yet, but that should not be significant. It involves machining the bottom surface flat and drilling 3 holes, two that bolt the manifold to the head and one that hold the exhaust tube in place. If you are interested in a set please email me your name, e-mail contact and phone number. When we get closer to casting time I will contact you. rustaddict1 at gmail.com
Maybe this should be in the classifieds. I don't know.
Happy happy joy joy!
Nope, you're in the right place, although you should probably also put this in the classified, and on the other early Ford forums, the go-fast folks, etc. Then you'll get a larger production run and lower costs/prices.
The reason this is in the right place is that you aren't really advertising a part for sale, but announcing the production of a part currently made of "Unobtainium" and you aren't doing this for the money (if anyone thinks that, do one of these projects!), but for the good of the hobby (OK, so you get a set for your car, but trust me, you'll still pay dearly for them! ).
Although I don't need them, THANK YOU for undertaking this for all the folks that do need them!
Patterns should be back this week. We will then cast one to see how it goes. The mold will add 3/32 on the bottom so that we have plenty of material for machining. The exhaust port will be slightly less than 2.25" so that they can be machined for a good fit. Once we have the first one I will get the cost to machine the whole batch. There are ads coming out in the April issues of FAST and SSOS magazines. The more we have made, the cheaper they will probably be. This will most likely be a one run deal.
You are a brave soul, John Steele! Seriously, that is a great project and if I am correct you are having them cast in MONTANA, USA!! which I like. I don't have a very good mill, just a Jet Mill/Drill but you are welcome to come use it if you want to work on machining them.
Are they going to be Cast iron or Bronze??? Bronze ones would really look cool!!
Me thinks they might look cool in bronze- at least until you fired the engine, but they would most likely not stand up to the exhaust temperature for an extended period. Class 40 cast iron or 65-45-12 ductile iron would be my choices.
Thanks for the update!
Sounds good !!
John, here's that photo I was telling you about.
Bill France Sr. (founder of NASCAR) in a Model T racer in 1931 which appears to have a Laurel head with competition exhaust manifolds.
Here is the first casting of the exhaust manifold. I went to the foundry on Thursday and picked it up. This coming week I will try and get some estimates on the cost to machine these. The foundry is supposed to get me a cost figure this week also. I have ads coming out in the April classified of FAST and Secrets of Speed magazines. Although it will not make a huge difference the more we cast the cheaper they will be. Again cost will be figured by adding up all expense and dividing it by the number cast. I'm paying the same for mine as everyone else. The museum of American Speed will get a pair donated to them which is being spread among everyone.
Ross and Diane Harris Smith are the people who so kindly handed over one of their exhaust manifolds to copy at the Speedster Reunion Lincoln NE last year. We did not know each other and they were brave and trusting enough to do that. I'm extremely grateful to them for that. With out the Speedster Reunion we would have never met.
Nice looking casting!!!
Pretty excited! Thanks again for the update!
Happy to report I received my manifolds from John. Grinning from ear to ear. Thanks John, The speedy Bill museum and anyone else involved.
John is in eastern Montana Deer hunting. He may or may not have internet access. I think he has one more set of these. It might take him a few days to get back to you if you are interested in a set.
Seeing photos of these manifolds on a head are impossible to find online, I thought I'd show them off just mocked up.
Mike I have ordered a set from John but am still awaiting them. I like your rocker covers. where could i get a set.
Les Schubert makes the rocker covers. He is often active on this forum. Here is his contact info.

I do have the patterns for the covers pictured. If there is sufficient interest, I could take them to the foundry on the weekend. No, I don't know a current cost, but they will be reasonable !!
My preferred method is PayPal
thanks Les I am definitely interested.I am in New Zealand and Have a 1926 Roadster. paypal is good for me and Fed Ex for freight. Here's hoping there is enough interest. Cheers Lee
Seems like 2 sets, so sure I'll go ahead
Not meaning to "hijack" the thread, but I see I have a spare new casting of the model "B" exhaust cross pipe and "dogleg" connector for the exhaust system. This is for the standard performance 16 valve Roof
Les i'm not aware what that looks like could you post a picture please?
This is the part he reproduced.
It attaches to this manifold.
And when installed looks like this.
thanks for that Mike. I haven't got one of those manifolds so i will stick to Johns ones for now.
Thank you Les for the offer.
Where do I get a set of pushrods from please?
Pushrods; you make them!!
Good news is I found the cover patterns!! So hopefully in a week or two I will have the castings
Thank you for the pictures
great news Les. Yes i will buy a pair from you please. Please advise price and freight. i prefer Fed Ex and paypal. Just watched to All blacks play Ireland then wife made me mow the lawns. Now for Coffee
