I am looking for a blueprint or photocopy of a cylinder from the 1923 Chevrolet Series M copper cooled engine. I would like to compare it to an air-cooled cylinder we found in a barn. We are very sure that it is not a cylinder from a Delco Light plant. I have looked online at photos of the Chevy 4-cylinder engine and the cylinders look very similar.

Hi Paul

Is this is the same cylinder you posted the picture of in a previous thread... https://vcca.org/community/general-discussion/chevy-air-cooled-engine/#post-4170

If so, you can be 100% sure it is NOT from a Copper Cooled Chevrolet for the reasons I gave in that thread:

It appears to me that you are looking at a cylinder that is NEITHER from a 4 cylinder air cooled Chev or a 4 cylinder Delco light plant engine, and must be in fact from a single cylinder engine.

I say this because the flanges for the intake and exhaust are on opposite sides of the cylinder, and in-line with the axis of the rocker arm shaft.

That would be impossible on any in-line multi-cylinder engine, and puts the intake and exhaust on OPPOSITE sides of the engine this cylinder belongs to.

Both the Copper Cooled Chevrolet and the 4 cylinder Delco had both manifolds on the SAME side of the engine.

Just my thoughts. 

The configuration of the cylinder in the picture you posted would be impossible on a multi-cylinder engine with the push rods on one side of the engine and both manifolds on the other.

Hope that helps you in your search for the cylinder's identity.  🙂

it does help and I try to do research on things like this cylinder. I did not know about the technical document site until now. I thought well, nothing gained and nothing to loose by asking. I would rather take the time to learn than to announce "look what I found" as a fact. Thanks for your help for my freind and myself in searching about the cylinder.
