Just like Ultima’s® EVO® style engines this engine features high quality components at an affordable price. These cases utilize Timken sprocket shaft bearings. The crankshaft assembly is the same crank assemblies Ultima® has been building for years. Dynamically balanced and featuring forged H-beam rods makes for a rock solid foundation for these engines. Pistons are forged aluminum from Mahle Motorsports®. The heads feature conical valve springs, chromoly retainers, manganese bronze guides, compression releases and stainless steel valves. Valve train components include an Andrews® 67H set of cams. Ultima’s® 4140 steel adjustable pushrods and topped off with 4140 forged steel roller rockers. The cam chest components include a billet oil pump, billet cam support plate with late model hydraulic chain tensioners for peace of mind. Choices of finish include black, polished or silver. With plenty of power these engines make a great replacement for a tired stock motor or a custom build.
