Hot Bike Staff

The Delkron 120ci Square Block ($8,232.95) is a complete plug-and-play powertrain, so you can just unplug your tired old H-D Evo motor and hook this fire-breather up to your ’99 and earlier Harley-Davidson Softail as well as ’98 and earlier DYNA, FXR, and FLT with no chassis modifications needed. Constructed from A356-T6 aircraft aluminum castings, the Square Block hits the dyno at 121 hp and 138 foot-pounds of torque, has a 4.250-inch bore and stroke, and 10.5:1 compression. This massively masculine engine is also chock-full of some great components, such as a five-piece crank featuring a trued and balanced H-beam rod, Wiseco 10.5:1 forged pistons, proprietary billet oil pump, Delkron cylinder heads and jugs, Andrews EV72 cam, Andrews adjustable pushrods, S&S Super G carburetion, and a Modotek programmable electronic ignition. Topping off the who’s who of parts are 6061-T6 billet rockers housings, rocker arm supports, and cam cover making this a mega motor for the money.
