Before Ordering
Confirm that your specific block requires first-design cam bearings. The first-design designation refers to the cam bearing configuration, not the engine's generation. Model year, displacement, and engine code alone do not establish fitment, especially around design changes or with replacement blocks.
For blocks using a later cam bearing configuration, confirm the correct alternative before ordering. Verify cam bearing housing dimensions, camshaft journal dimensions, installed clearance, and oil-feed alignment during assembly. Contact 3V Performance for help matching the bearing set to your block.
