Before Ordering
The existing application notes specify that these wider third-design bearings also fit compatible second-design blocks. Confirm CH-25 suitability for your particular block and camshaft rather than relying on engine family alone. This is the stock-size version, not an oversize kit for enlarged housing bores.
Verify housing dimensions, camshaft journal dimensions, installed clearance, and oil-feed alignment during assembly. Contact 3V Performance for help confirming the correct cam bearing set before ordering.
