I did some reasearch when I had my town car and it has a detuned version of the tv 4.6 mustang engine or more correctly the mustang had a tuned up version of the town car engine. If I remember correctly the 95 town car has 190 hp and 280 ftlbs torque. The 04 still has the 2v engine but w 240hp /300ftlbs, the same as early 2v4.6/96-97mustangs.
The maurader is an awsome car with the 4v "cobra" engine and 300 hp stock. Same body as the 03-11 town cars. Your 95 shares the body with similar year crown vics and mercury grand marquis only differance, lights and grills.
