Product Details

The Speedmaster PCE276.1042 is a 4340 forged steel crankshaft engineered for Ford 289, 302, and 5.0L small-block engines demanding increased performance. With a 3.400" stroke, 2.2486" main journal diameter, and 2.123" rod journal diameter, this internally balanced crankshaft delivers the precise tolerances required for high-horsepower street and race engine builds.

Key Features:

  • 4340 Forged Steel Construction — superior strength and fatigue resistance over cast iron OEM crankshafts
  • Precision Ground & Micro-Polished Journals — ensures tight tolerance control and smooth bearing surface contact
  • Nitride Hardened — provides exceptional wear resistance and extended service life under high-stress conditions
  • Shot-Peened Finish — relieves surface stress and increases resistance to cracking and fatigue failure
  • Heat Treated — optimizes material hardness throughout the forging for consistent strength
  • Straight-Shot & Chamfered Oil Holes — promotes efficient oil delivery to main and rod journals
  • Lightening Holes in All Rod Throws — reduces rotating mass for improved engine response and RPM capability
  • Large Radius on All Journals — maximizes strength and wear resistance at high-stress transition points
  • Internal Balance — compatible with internally balanced Ford small-block engine assemblies

Specifications:

  • Stroke: 3.400"
  • Main Journal Diameter: 2.2486"
  • Rod Journal Diameter: 2.123"
  • Balance: Internal
  • Material: 4340 Forged Steel
  • Application: Ford 289 / 302 / 5.0L Small Block

The PCE276.1042 is a direct upgrade for builders seeking a reliable, race-proven bottom end solution for Ford small-block applications. Fully inspected prior to shipping, this crankshaft is ready for professional engine assembly.
