I always wondered why the Police Interceptor, didn't get a big horsepower boost. Ford marked it out @ 250hp, which even for the big sedan, was good for over 125mph easy. However, it always was labeled a slug...
My "slug" lasted 15 years, with over 300K on it. I have heard the same from taxi drivers. Used some oil, but the valve covers never had to come off, and the tranny was still virgin.
Had a Ford rep tell me, that they kept the PI71 motor fairly tame, because it allowed a high-rev, small displacement engine to last much longer.
Thoughts?
