Says Chevy '41 Up right on the box. Barry was pretty good at keeping track of the applications. The only question is how far "UP" is.
[on edit] The 1929-1954 Parts Catalog says the same water pump repair kit fits all engines between 1937 and 1954 (and maybe later).
[another edit] The 1929-57 parts catalog doesn't list water pump repair kits, but some water pump parts, such as rotors and seals.
