Enginetech BB608J

Enginetech BB608J is a connecting rod bearing set for Ford 351W / 5.8 Windsor engines. Rod bearings are precision components and must be selected by rod journal diameter, STD/undersize variant and intended oil clearance.

Application / fitment

The set is intended for selected Ford 351W / 5.8 Windsor engines from approximately 1969–1997. Typical applications include selected Ford, Mercury and Lincoln models with the 351W engine, but final compatibility depends on crankshaft condition and bearing size.

• Ford 351W Windsor / 5.8 V8
• selected Ford Mustang, Torino, Ranchero, LTD, Thunderbird, F-Series, Bronco and E-Series
• selected Mercury Cougar, Montego, Marquis and related models
• selected Lincoln applications with 351W / 5.8 engines, depending on year and crankshaft

Before installation, check rod journal diameter, bearing width, crankshaft fillet radius, bearing clearance and whether the crankshaft is STD or has been ground undersize. Available variants for this bearing family may include STD and common undersizes such as .010”, .020” and .030”.

Marine application: the BB608J part number is also listed for selected marine engines based on the Ford 351W / 5.8 platform. For this use, the bearings must be selected by the exact part number, rod journal diameter, STD/undersize variant and required oil clearance. Marine fitment is determined by the engine base, crankshaft and marinizer configuration, not by the boat model.
