Does anyone know if the oil pressure gauge for a 66 and 67 GTO are the same? Mine is a 66 gauge (according to the previous Owner) and it goes up to 80 psi. I think I have seen somewhere that the 67, 400 produced higher oil pressures and a different gauge that registered a higher pressure was used.

66 GTO HAD 60 PSI GAUGE AND EARLY 67 ALSO HAD 60 PSI, THEN 67 CHANGED TO 80 PSI

Thanks, I checked out the restoration guide and it confirmed what you indicated. I guess I have a 67 guage after all (this is a good thing).
