M-6009-427F- Ford Performance Parts
427 CUBIC INCH BOSS SHORT BLOCK
The Ford Performance 427 short block 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 9.5″ deck engine for your vintage muscle car, street rod, Fox Body or Late Model Mustang. This is the same short block used in the 575 HP Z427 crate engine. Nothing but the best parts are used inside including: forged crankshaft, forged I-beam connecting rods with floating piston pins and the BOSS 351 block. This short block is hand assembled with performance clearances in the US. The 427 short block fits many of the vehicles originally built with Windsor and Cleveland small blocks.
