Restoration work on high-mileage Crown Victoria, Town Car, Grand Marquis, and similar Ford applications

Installation Notes and Tips

Verify crankshaft journal condition, housing bore size, and oil clearance before assembly. Clean all bearing surfaces thoroughly and follow the engine builder’s torque and lubrication specifications during installation. Confirm that the engine is a Ford 4.6L Modular V8 SOHC application and match the bearing size to the crankshaft and block measurements before final assembly.

Quality Assurance

Speed Pro positions this component as part of its value-focused performance engine component line, with materials selected for rebuild and competition use. The 148M main bearing set is intended for Ford Modular V8 applications where consistent bearing support and proper fit are required.
