Before Ordering
Match CHP-23 to your specific block's cam bearing configuration. The housing bore values above describe the block bores, not camshaft journal diameters or assembled oil clearances. Engine family and displacement alone do not establish fitment.
Confirm the required bearing dimensions against your block and camshaft specifications. Verify installed clearance and oil-feed alignment during assembly. Contact 3V Performance for help confirming the correct bearings before ordering.
