363 CUBIC INCH BOSS SHORT BLOCK

 The Ford Performance Z363 shortblock lets you build it your way by adding your choice of heads, cam, intake and oil pan.  It's the perfect foundation to build a powerful 8.2" deck engine for your vintage muscle car, street rod, Fox Body or Late Model Mustang.  This is the same shortblock used in the 500 HP M-6007-Z2363FT crate engine.    By taking the bore out to 4.125-inch, the displacement of the popular 347 stroker has been increased to 363 cubic inches. Nothing but the best parts are used inside including: forged crankshaft, forged I-beam connecting rods with floating piston pins and the BOSS 302 block. The Z363 shortblock fits many of the vehicles originally built with a 289 or 302 8.2-inch deck height block.
