This 124 cubic inch T124 high compression Long Block engine fits 2007-'16 HD touring except Twin-Cooled models. Long Block engines do not include a fuel or ignition system, 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. Engine features 4-5/8" stroke X 4-1/8" bore at 10.8:1 compression, S&S 640 gear drive Easy Start cams, S&S TC3 oil pump and cam plate, and Stone Gray powder coat finish that matches CVO granite engine components.
