S&S T143 Long Block Engine With Easy Start Camshafts For Harley

If you want to build the baddest bike on the block, you need a T143! The S&S T143 Long Block engine is the largest S&S engine that will fit in a stock Harley- Davidson chassis. At double the HP of a stock motor the power of the T143 requires technical expertise for the installation and tuning along with an experienced rider. This is an ultra performance/race engine. Longevity, engine noise, vibration and throttle sensitivity have all been compromised to reach this level of performance while fitting in a stock chassis and as such is not suitable for every situation.

Features:

  • S&S Cycle Super Stock crank cases with reed breather valve
  • S&S Cycle B3 cylinder heads CNC machined with 2 bolt exhaust flanges
  • S&S Cycle 3 Piece Flywheels
  • S&S Cycle TC3 cam plate and oil pump
  • S&S Cycle 635 Easy Start gear drive cams
  • S&S Cycle 1.725:1 rocker arms for .674" total lift
  • S&S Cycle Premium High Performance Tappets
  • Requires high performance ignition system, sold separately 
  • Requires S&S Cycle Super G or Super D carburetor kit, sold separately
  • Requires S&S Cycle Oil Line Kit and S&S Cycle Transmission Drill Fixture, sold separately
  • 1 Year Warranty
  • Made in the USA

Note: The S&S T143 engine comes with S&S B3 Special Application cylinder heads. Due to the unique exhaust port configuration, stock exhaust pipes will not fit. You ca either use the S&S Cycle T143 Exhaust Flange Starter Kit to adapt existing 2” headers or fabricate a whole new system.
