Does my 2000 GT have a "PI" Engine???

Can't say I know crap about 4.6s, but I'm pretty sure the 99+ GTs are PI motors. All the 96-98 guys want the PI heads & cams to get up to part with the 99+ guys. Thats why the 99+ is rated at like 260hp and the 96-98 is along the lines of like 220-230hp...not real sure.
