Hi, I have noticed a lot of conversation about the Sherman Super Fire head. I was asked to post that I am producing the heads again from the original patterns. They are made from 356 T6 alloy and fully machined and ready to go. I have 10 available now. I also have Sherman sumps and valve covers. If interested you can e-mail me at firstname.lastname@example.org. Thanks, Ben Serar
Are you casting any LOW heads?
I'm interested in a Sherman head. E-mail sent. Any photos? How much are they? The 1970's Shermans were made in different versions with various compression ratios as I've heard. What's the combustion chamber volume in your new heads?
In this link the Tulsa model T club compares volumes in various heads and calculates the corresponding compression ratio: http://mtfctulsa.com/Tech/head_design.htm (unfortunately no Sherman head)
Ben, how about the 8N Sherman head? There would be a great market for them as there are a lot of red bellys around. I sure would like to find one.
Having run one before I really like the chamber shape
I have heard of a Sherman Super Fire and Spit Fire. Maybe even a Sure Fire, but not an 8N. Can you provide some details on this head?
I had a Super Fire on my speedster and loved it. The Waukesha Ricardo I have now does not have the same kick.
I think what he is talking about are the heads that were made for the 8N Ford tractors.
Stan is correct. They were acc. for the 2,9 and 8N Ford tractors made in 39-53. A repop of that head would be a highly desirable item.
Ben sent some pictures. Apparently a full line of Sherman accessories are available:
Plug size options? Is the tap for a temp sensor? Looks great from here.
What was the difference between the "super Fire" and "Spit Fire"?
I've seen older Sherman heads that had twin spark plug capability - are those going to be available ?
I have a spare Sherman sump that was used as a mold to make a bunch of copies. The holes are still filled with putty.
I sold this clean Sherman Spitfire Cylinder Head for $250 two years ago.
I have been running a Sherman Super Fire head on an otherwise-stock 1926 Roadster PU...since 1979. A good performer. Don't know the compression ratio. Paid $300 new for the head. The car has seen a lot of action in the past 40 years since restoration... could use lots of cleanup and cosmetics.
I had one 25 years ago and it worked well.
I put one on a speedster in 1977. Engine had a counterbalanced pressure oiled A crank, big cam and Holley 94 carb. The car would do 100 mph!
I am glad to see these heads back in production. I always liked the racy look, and also like the combustion chamber design. I have an original that is 214 cc (5.1 CR) or about the same as a Z head. Before it went to the museum, I measured 172 (6.3 CR) for the twin fire head on the Pietenpol. I don't know how many different variations there were, so I have never put these numbers on the Tulsa website. It would sure be nice to have a true 6:1 CR head available rather than one that is falsely advertised as such.
