NEW! 120" Square Block Complete

Delkron's assembled 120" Complete Square Block engine (4.250" bore with 4.250" stroke) will fit the stock Harley-Davidson® Softail® (1999 & earlier) chassis as well as Harley-Davidson® DYNA™ (1998 & earlier), FXR and FLT with no chassis modification.

Our 120" Square Block ships fully assembled and has all the components of our long block, but has been finished off with a recipe that has yielded a modest 121 HP and 138 lbs. of torque at the rear wheel. This is a complete plug and play system including carb and ignition. Just unplug your old tired Evo and hook this fire breather up to your stock charging system and driveline! Then HANG ON!
