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 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. 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. 1 Year Warranty Note: Not legal for sale or use in California on any pollution controlled motor vehicles.
