This done first temporarily to test fit things. The the elbows can be permanently installed as directed. Be careful to determine if your Elbows require spacers. Mine did not. The intake manifold should not be permanently installed nor should the AeroInjector until fter the motor is mounted.
Also after mounting I needed to adjust (bend) the mounting tab at the bottom of the intake manifold and fabricate parts and spacer to attach it to the engine securely.
