Description for S&S Cycle T143 Long Block Silver Engine

• Fits in stock chassis – no cutting or frame modifications
• S&S Cycle B3 cylinder heads CNC machined with 2 bolt exhaust flanges• 3 Piece Flywheels• S&S Cycle high flow oil pump and cam cover• S&S Cycle 635 Easy Start Gear Drive Cams and S&S Cycle 1.725:1 rocker arms for .674″ total lift.• S&S Cycle Premium High Performance Tappets• Requires S&S Cycle Super G 743-813 or Super D 743-812 carburetor kit which includes the carburetor, manifold, air cleaner kit, and all hardware required.• For improved ridability, S&S Cycle recommends the Super G carburetor. It has better low RPM throttle response and offers better control in lower RPM applications.• The Super D carb kit is recommended for race applications where high RPM horsepower is the most important factor.• The Super D carb kit is not recommended for use on Touring models. The length of the carburetor and air cleaner assembly makes it very hard to reach the rear brake pedal.Recommended for Dyna models with mid controls only.• S&S Cycle T143 engines must not be run with a stock ignition system. A special ignition advance curve is required to prevent serious engine damage.• S&S Cycle recommends the Dynatek 380-994 ignition system for 1999-’03 models, and the Dynatek 382-359 for 2004-’06 models. The Dynatek Programming Kit 382-664 allows S&S Cycle ignition calibrations to be loaded directly into the module from your PC.• Ignition calibration files for the T143 engine with a Dynatek ignition are available on the S&S Cycle website under the Tech Info tab.• Dyna Models – Require custom exhaust. We recommend S&S Cycle exhaust flange kit – 743-818 as a starting point for building a custom exhaust system.• 1 Year Warranty
