S&S T124 ENGINES (HIGH COMPRESSION)

The ultimate power producing and reliable drop in engine available! This engine features high compression and a massive 640 cam for higher rpm riding. It is still a streetable engine that's built for more of a race style rider. If you're into more long distance / touring riding we recommend the low compression version with the 585 cam or the T111. We've being installing these motors for years with nothing but an excellent experience! 
 
This S&S 124 cubic inch T124 Long Block engine fits '99-'06 Twin cams (Except '06 Dyna) . 2007-'16 HD Touring bikes (Except Twin-Cooled models) or '06-'17 Dyna. Long Block engines do not include a fuel or ignition system, so If you already have a larger throttle body and EFI tuner, they can be used with this engine. The cylinder heads are specially machined to compensate for the longer cylinders so a stock length manifold or throttle body will fit perfectly, and the cylinder head breathers are compatible air cleaners designed for a stock engine. Stock non programable engine management systems should not be used because they are not designed for an engine this large. 
  
 The easy start cams makes starting easier however a high torque starter is recommended.
