Pontiac 400 Cast Steel Crankshaft 3.750 Stroke

The Pontiac 400 Cast Steel Crankshaft 3.750 Stroke is a precision-engineered internal engine component designed for automotive enthusiasts rebuilding or upgrading the classic Pontiac V8 platform. As the backbone of the rotating assembly, this crankshaft is specifically tailored for those seeking a reliable alternative to factory iron units during high-performance street or mild racing builds. It provides the necessary structural integrity to handle increased torque loads while maintaining the iconic 3.750-inch stroke that Pontiac purists demand for their engine restorations.

Constructed from high-tensile cast steel, this Eagle crankshaft offers superior strength and durability compared to standard OEM cast iron alternatives. The 3.750-inch stroke is meticulously machined to ensure precise timing and balance within the block, reducing parasitic drag and internal vibration during operation. By utilizing cast steel, the manufacturer provides a robust grain structure that better resists the stresses of increased compression ratios and aggressive cam profiles found in modified engines.

This Pontiac 400 Cast Steel Crankshaft 3.750 Stroke is ideally suited for 400 cubic inch Pontiac blocks, serving as a direct-fit replacement or a foundational piece for a new rotating assembly. Professional engine builders and DIY mechanics alike will appreciate the consistent journal tolerances, which simplify the bearing selection process during final assembly. Whether you are finishing a numbers-matching restoration or building a weekend cruiser, this component ensures long-term reliability and smooth power delivery for your classic American muscle car.
