Pontiac 400 Forged Crank 4.250 stroke

The EAGLE Pontiac 400 Forged Crank 4.250 stroke is designed for serious engine builders and classic car enthusiasts who require a reliable foundation for high-performance Pontiac 400 applications. This forged crankshaft is ideal for stroker builds, racing engines, and street machines that demand exceptional durability under high power conditions.

Constructed from forged steel, this crankshaft significantly enhances fatigue resistance compared to cast alternatives, making it suitable for high RPM operation and elevated cylinder pressures. The 4.250-inch stroke geometry increases displacement and torque characteristics, allowing for substantial cubic-inch growth when paired with compatible connecting rods and pistons. Its robust journal design and precision manufacturing ensure optimal concentricity and balance, which are crucial for reducing vibration and extending bearing life.

Engine builders and mechanics frequently choose EAGLE crankshafts for Pontiac restorations, street rod builds, and vintage drag racing applications where reliability and performance are paramount. This component integrates seamlessly into traditional Pontiac 400 engine blocks while maintaining factory bore spacing and mounting conventions, making it a versatile choice for various performance builds.
