VCCA Home Forums TECHNICAL - 1945 AND EARLIER 1912-1928 28 Chevy manifold

I went to a swap meet in Springfield Mo. this weekend. It kinda sucked for a guy like me who went there hoping to see something old. One guy had a few 4 cyl Chevy items, one of which was a 2 port heater type exhaust manifold with heat exchanger and the tin andfloor grate. It looked complete. He had a sign out to ask about other 4 cyl Chevy items so I struck up a conversation with him. Pretty soon he commented that the heater would fit 24-28 models. I said I was under the impression that only 1928 had two exhaust ports. He said his 26 had two ports and that he had factory literature for 1926 showing two ports and pushrod covers. I did not argue with him, I only said that I had never seen any such literature or a pre 28 engine with these features. After all, he was the expert, he was the one with the sign. Can you guys straighten me out on this?

Hi 35Mike,

You would like to believe a fellow who was telling a story, but sometimes the memory gets a bit shaky. The exhaust heater that you described was a new accessory for 1928 and is covered in the CSN for 1928.

It is also possible that the fellow had actually seen that heater on a 1926, however it would have to be a 1928 head for the Chevrolet heater to fit. I have seen after market heaters on the early (single exhaust port) engines, but not a Chevrolet unit.

It would not be correct to tell the old fellow that the factory literature for an earlier heater does not exist. Strange things have popped up in the past.

For example, in the book "100 years of the American Auto" on page 97 is the picture of a brochure advertising the installation of a Westinghouse radio in a 1922 Chevrolet for $200.00. This brochure appears to be 4 pages and each page sports the Chevrolet Bowtie????? It shows a picture of the car with the radio installed.

So it would be dangerous to tell the fellow he was wrong about such a piece of literature.

Mike and Ray,
You might notice that I deleted the thread in the 29-32 forum to keep confusion to a minimum.

Hello again,
I guess I was not clear about my conversation with the vendor. He did not say he had seen the heater illustrated in Chevy literature. He said he had factory literature showing a 1926 Chevy with 2 exhaust ports on the head and pushrod covers. Is this possible? Or should I say, is this likely?
Mike

It is not likely, however see my comments in the above post.

It has been a common practice for years to place the 1928 two port head on earlier blocks. So common that he could have became confused as to what he saw.

I would also add that in the past I have run the 28 Head and the heater set up on my 27 block and everything works fine except there is no correct way you can attach the pushrod covers to the 27 block. This would be the case for the earlier blocks also.
