Police V8, something different???

Hi!

I bought a 91 V8 that was once in the possession of the police. It was a freeway car. Does anyone know if there are changes to engine, ECU etc. The Commission's proposal is a very important one, and it is a very important one.
According to the previous owner, he is aiming extra in the doors and the side bars (I still have to look) and should have run 285 according to Tacho. It's a five-speed switch.
