Want to build a powerful Ford engine for your vintage muscle car, street rod, Fox-body or late-model Mustang? A Ford Performance short block is the perfect foundation. Ford Performance Engineers have taken care of the toughest part of building a new engine by designing a strong a durable short block that offers a wide range of power possibilities. We use only the best parts for our short blocks, like a forged steel crankshaft, forged H-beam connecting rods with floating piston pins, forged Mahle pistons, and the Ford Performance BOSS block.
