The valvetrain is hydraulic. This long-block assembly is available in three finishes: all-Black Edition, Chrome with Wrinkle Black, or Chrome with Natural finish, allowing for aesthetic customization to match your build. The engine is proudly made in the United States.\n\nFitment encompasses Harley-Davidson 1984-1999 Evolution Big Twin chassis within the Softail, FXR, Dyna, and Touring families. It is important to note that the larger stroker flywheels may necessitate additional primary-side clearance in tight-clearance stock chassis applications; confirmation with S\u0026amp;S Cycle or your installer is recommended. This long-block scope requires the installer to supply the carburetor or EFI, ignition system, and chassis-side primary, transmission, and exhaust components.","brand":"Harley-Davidson","offers":[{"title":"Default Title","offer_id":52688642769208,"sku":"SS-V124-LB","price":6799.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/663691766.webp?v=1784892230","url":"https:\/\/store.motormia.co\/products\/v124-evolution-long-block-engine","provider":"MOTORMIA","version":"1.0","type":"link"}
