The Heart of the Rebuild: NOS Internal Engine Parts

When you are rebuilding a vintage engine, "close enough" tolerances lead to failure. You need components that match the original metallurgy and weight of the factory design. At Old Car Parts NW, we specialize in NOS (New Old Stock) and NORS internal engine parts from the golden era of American manufacturing.

Build It to Last

  • Pistons & Rings: We stock authentic Sealed Power, TRW, and Sterling pistons. Unlike cheap modern castings, these often feature the correct alloy composition for vintage block expansion rates.

  • Camshafts: Restore your power band with NOS cams and lifters that are precision-ground to factory lift and duration specs.

  • Bearings: Protect your crank with Clevite 77 and Federal Mogul Tri-Metal bearings, the industry standard for durability.
