The only difference between the cop car and normal crown vic is suspension and cooling mods. MOST cop cars had dual exhuast which was a 10hp improvement over stock. The shocks and springs are heavier duty and the ALT. is bigger, the radiator hoses are usually blue silicone for more burst strength. The Mark 7 is a good choice just watch for busted air bags in the suspension. Other than that any mod that bolts to a stang 5.0 bolts to a Mark 7....and you can even do a 5spd swap fairly easy.
