 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.
