THE GOAT Ford 347 Crate Engine

THE GOAT Ford 347 is the “street torque” small-block choice when you want your Ford to feel stronger everywhere—especially through the midrange—while keeping classic small-block packaging.

Built around a seasoned 1987–1995 OE roller block, it combines forged internals, a hydraulic roller cam, and a matched supporting combo (balance, fuel, ignition, oiling) designed to drive clean and hit hard in real street RPM.

At-a-glance (why this combo works)

• 415 HP / 430 TQ tuned for the street RPM range with a clean hydraulic roller setup
  
• 28oz external balance with matched balancer + flexplate/flywheel
  
• Supporting parts selected as a system (oiling, ignition, fuel, and drivability notes)
  
• Warranty included: one year, unlimited mileage written warranty
