FWIW, I believe the smog devices associated with the various Panteras are:
'71-72= a PCV valve in place of a road draft tube for crankcse venting.
'73-74= a PCV + the cam was retarded 4 degrees and the ignition timing advanced 4 degrees. A thermal switch & solenoid advanced engine speed when engine temp approaches 200F (this might not have been smog mandated but was simply to make the preceding two mods actually driveable).
'81-up= PCV, smog pump plus dual catalytic converters.
I could have some details scrambled. If its vital to someone, KRE of Amerisport in OH was intimately involved in this nonsense as the U.S "manufacturer" of the Pantera GT-5 and GT5-S, so he would be the one with all the correct info.
