Product Description
Genuine Johnson Bronze Set No. 104 Cam Bearing Set (NOS)
Maintain precise valvetrain geometry and oil pressure in your classic Stovebolt engine with this genuine Johnson Bronze New Old Stock (NOS) cam bearing set. Precision-manufactured in New Castle, PA, these bearings feature high-quality lead-based babbitt on a steel backing, designed specifically for the final generation of the Chevrolet 235 and 261 cubic inch inline-6 engines. This specific set is a .010 undersize (written as .010 on the box), intended for engine blocks where the camshaft journals or bearing bores require a tighter fitment to compensate for wear or machining. These are the correct components for the "Blue Flame" six-cylinders used in Chevrolet passenger cars, trucks, and early Corvettes from 1954 through 1962.

Note on Photos: The images provided are of the actual item you will receive. Please inspect the photos carefully to confirm the condition and specific features of the part.

A Note on Fitment Accuracy: We manually research and cross-reference our fitment data using vintage manufacturer catalogs. While we strive for 100% accuracy, these decades-old resources—and the humans reading them—can occasionally contain errors. Additionally, these parts may fit other vehicles and years not explicitly listed in our data. To ensure a seamless restoration, we kindly ask that you perform your own due diligence and verify that this specific part number is correct for your application prior to purchase.
Unbeatable Prices & Expectations
While many of our vintage parts were manufactured decades ago, they remain unused and high-quality. Some original boxes may show signs of shelf-wear, such as dust, tape, or surface distress from years of storage. Rest assured, the components inside have been inspected to ensure they are complete and ready to help you finish your project without breaking the bank.
