Technical Highlights

- Application/configuration: Ford 289-302

Selection Guidance
The specified cap arrangement, block design and windage-tray requirements determine which kit is appropriate. A similar displacement or engine-family name does not establish that different main fastener kits are interchangeable.
Confirm the block, main-cap arrangement and any girdle or windage tray before ordering. Plan these checks before final machining and bearing selection. Pay particular attention to the stated with 1/2 in Straps configuration.
Installation Considerations
Have the engine builder check main-bearing bore size and roundness with the intended fasteners installed at the specified preload. Align-hone if required, using the same hardware and lubricant intended for final assembly. Follow the kit-specific instructions for thread preparation, washer placement and tightening.
