Ultima El Bruto 107ci Evolution-Style Engine for Harley-Davidson Natural Finish

Prepare yourself. Ultima is now offering the new "El Bruto" series engines, made in America for your Harley. True to their name, the 4" bore 107 inch El Bruto engines have horsepower to spare. They are the most powerful EVO configuration of these sizes. All of the castings in these engines are poured in US foundries and are based on all-new CAD designs cast from C355 aluminum: a common US military alloy known for its stability over multiple heat cycles. Comes complete with carburetor ignition and warranty.

This beast has a large bore breather for increased crankcase vacuum and less blow-by, 1/2" alignment dowels for true line bore, counterbored stainless allen head case bolts, plus styling and cosmetic machining for a custom look.
