Fuel or ignition system not included.
All clearances and assembly specifications will need to be checked.
Although the engine is 0.960" taller than stock, there are no frame clearance problems, and a stock EFI throttle body will fit because the manifold mounting surfaces of the heads have been specially machined to fit a stock length manifold.
