Internal Engine Components
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.
The Brain of Your Engine: Camshafts, Lifters & Timing
The camshaft dictates the personality of your engine. Whether you are looking for a smooth factory idle or a lumpy muscle car "chop," we have the parts to make it happen.
Cam & Lifter Failure Vintage engines with flat-tappet cams require high-zinc oil. If your cam lobes have wiped out, we stock authentic NORS Camshafts and Lifters (Mechanical and Hydraulic) to restore your valve lift.
-
Timing Components: Don't forget the Timing Chain and Gears. A loose chain causes erratic timing and poor performance. We stock silent nylon-coated gears and heavy-duty double roller sets.
Power & Compression: Vintage Piston & Ring Sets
Whether you have a cracked piston or just want to bore your cylinders for more power, we have the reciprocating mass you need.
Cast vs. Forged
-
Cast Aluminum: The factory standard for smooth, quiet operation and longevity in street cars.
-
Ring Sets: We typically sell pistons and rings separately or as kits. Look for Chrome or Moly rings for superior sealing.
-
Sizes: Standard, .030, .040, and .060 oversizes available for most popular V8 and Inline engines.
Breathe Deep: Valves, Springs & Pushrods
The valvetrain controls the flow of air and fuel into your engine. Worn guides, weak springs, or bent pushrods will kill your performance.
