Ford Racing has taken its Boss Block to the max with the biggest small block Windsor crate engine ever – the Z460.  With 575 horsepower and 575 Lb. Ft. of torque, Z460 packs a pump gas fueled punch that works well on the street and on the track. 

The foundation of  the Z460 is the legendary Ford Racing Boss block topped off with high port/high flow Z-Heads.  Premium components from the best aftermarket companies are used throughout the engine, like a SCAT® forged steel crankshaft, SCAT® forged H-beam connecting rods, forged Mahle® pistons and Clevite® bearings.  And every Ford Racing Z460 engine is hand assembled in the U.S. with performance clearances.
