Just getting started on this 1940 KC. Project was started by someone I don't know...I bought it from a 3rd party.
From what I think I have found in my research, I believe the engine is a (freshly rebuilt?) 1954-55 235ci (block casting number 3835911), (head casting number 3835913).
I am attaching some photos of the carburetor and the intake. I don't know what the model of the carburetor is. Is it one of the visible numbers cast into the brass?
I am wondering if this is the proper setup for this engine.
I am a ways from being able to try starting the engine...there is not a usable wire on the truck.
I don't believe any Chevy came with a Stromberg carburetor. I believe they all came with a Rochester. If I'm wrong someone will point it out. Whether the Stromberg will work or not I don't know. Someone will be along who can answer your question. Good luck with your project.
