Detailed Description

Part number 663 is an engine piston ring set for standard-bore 3.4375-inch six-cylinder engines. The ring package uses grey iron for the top and second rings, with phosphate treatment on both, while the oil control ring combines a steel rail and stainless expander with a chrome surface treatment. Groove dimensions are listed as 5/64 inch for the top and second grooves and 3/16 inch for the first oil groove, which helps match the ring set to the specified cylinder block configuration. This part number 663 is listed for classic Dodge truck and Chevrolet Corvair applications, including Dodge W300 Pickup, Dodge W300 Series, Dodge D300 Series, and Chevrolet Corvair models.

What It Is Used For

  • Addressing oil control concerns from ring wear or loss of tension
  • Replacing standard-size rings during engine overhaul work
  • Matching ring groove dimensions during block rebuilds
  • Supporting compression recovery in listed classic engine applications

Installation Notes and Tips

Verify bore size, groove dimensions, and cylinder count before installation. Confirm that the engine is a standard 3.4375-inch bore application and compare the listed groove measurements to the piston and block specifications. Fitment includes 1954-1968 Dodge truck and power wagon applications plus 1961-1963 Chevrolet Corvair and Corvair Truck listings. This part cross-references Monroe Shocks & Struts (e.g., 303P, 5691X) for the same application.
