Hey, The SFC can be calculated via the SFC Calculation Library Block. Gross thrust can be summed up from the nozzle components (Fg) and any other sources. Ram drag can be taken from the Ambient block. It is within the A_Data bus. Any other sources of ram drag should also be summed. The fuel is the same value that goes into the Wf input for the FuelFlwIn on the burner. An example of this is done in the AGTF30 package ( GitHub - nasa/AGTF30 )
