Description

  • Condition Details: Used mechanic-special/project condition. Every single cast component—including both black cylinder barrels, aluminum head assemblies, rocker cradles, and matching pistons—is structurally solid and completely crack-free with all cooling fins perfectly straight and intact. The inner cylinder sleeves show normal vertical scoring and light wear lines from field service and will require a professional machine-shop re-hone before assembly. All critical internal valve guides are true. Note: This listing is missing select minor mounting screws/hardware for the valve covers and rocker boxes but comes bundled with fresh head and base gaskets exactly as pictured.
  • Platform Fitment Bounds: Direct performance replacement, maintenance core, or performance upgrade for specialized RevTech 100" 4x4 Gen 2 or Gen 3 engine blocks. Also universally adapts to custom rigid frames, custom choppers, pro-street bobbers, and custom drag bikes running aftermarket Evolution big-twin style engine cases from 1984 to 1999 built to handle oversized 100-cubic-inch cylinder spigot clearances:
    • Fits Custom Chrome Inc. custom frames, Santee frames, West Coast Choppers, and similar custom builds configured for Evo-pattern drivetrains.
