S&S T143 ENGINES
The ultimate power producing and reliable drop in engine available! The biggest and baddest engine S&S offers. Features S&S's massive B3 CNC cut heads and 635 easy start cams with 1.725:1 ratio rocker arms for .674" of lift! Still fits in the factory frame with no cutting or modifications needed. 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. It is the purchaser's responsibility to consider the suitability for their application. Engine noise and damage from abuse is not covered under warranty. We've being installing these motors for years with nothing but an excellent experience!
This S&S 143 cubic inch T143 Long Block engine fits '99-'06 Twin cams, 2007-'16 HD Touring bikes (Except Twin-Cooled models) or '06-'17 Dyna. Long Block engines do not include a fuel or ignition system. Special fuel delivery systems are required. Specific T143 exhaust port sized exhaust also required. Stock non programable engine management systems should not be used because they are not designed for an engine this large.
