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. The engine components are machined on state of the art CNC equipment for guaranteed dimensional accuracy and repeatability. The Ultima carburetors are directly interchangeable with S&S Super G Carburetors. Ultima carburetors will accept S&S jets and S&S bolt pattern air filter assemblies. A relocated accelerator pump nozzle for increased throttle response and thunder jets are bolt on. Simply remove the plugs and screw in the Thunder Jet. No expensive machining required. This 6-speed transmission is complete, and ready-to-install
