To be brutally honest, the only thing "Police Interceptor" about the 5.0 was for extended maintenance, it had jack squat to do with making more power. The PI engines simply had oil coolers, p/s coolers, blue silicon rad hoses, and a few other small doodads to help them stay cooler at high pursuit speeds. If you think they were some mythical firebreathing option that instantly transformed a 5.0 into a 500 horsepower Ferrari slayer....you fail.
I may be wrong, but I think the last true PI engine was sometime in the 70's, or very early 80's..as far as having different internals than the "standard" same-displacement engine.
The SSP Mustangs, the PI Crown Vic's...etc....all have the same engine internally as any other 5.0 Stang/Crown Vic, respectively.
