Enginetech BB603J
Connecting rod bearings for Ford FE Big Block engines. STD or undersize size depends on the rod journal machining.
Enginetech BB603J is a connecting rod bearing set for Ford FE Big Block engines. These bearings are used during crankshaft service, short-block assembly and rod journal oil-clearance setup.
Application / fitment
The bearings are intended for selected Ford FE / Big Block engines requiring the BB603J rod bearing type. Compatibility should be confirmed by engine family, rod journal diameter, STD/undersize size and required bearing clearance.
- Ford FE / Big Block 352 CID
- Ford FE / Big Block 359 CID
- Ford FE / Big Block 360 CID
- Ford FE / Big Block 361 CID
- Ford FE / Big Block 389 CID
- Ford FE / Big Block 390 CID
- Ford FE / Big Block 410 CID
- Ford FE / Big Block 427 CID
- Ford FE / Big Block 428 CID
Typical automotive applications include selected Ford and Mercury models with FE engines from approximately 1961–1976, such as Ford Galaxie, Fairlane, Torino, Ranchero, Thunderbird, FE 390/428 Mustang, Ford F-Series and Mercury Monterey, Montclair, Park Lane, Cougar and Cyclone. In heavier applications, FE engines were also used in selected Ford utility and truck platforms. Final compatibility must be confirmed by the actual FE engine, connecting rod type and crankshaft configuration.
Before assembly, check the rod journal diameters, crankshaft undersize, STD/undersize bearing variant and required bearing clearance.
