My brother has an opportunity to pick up an '02 and '03 Crown Vic Police Interceptor from a local Police Dept. He's wondering if the 4.6's in them are any different than a regular 4.6.

From Wiki
It looks like 2004 the police interceptor got a boost but prior to that I see no evidence of the engine being differnt than the civilian model. I personaly think the 3 valve would be a better engine for the application(gobs more power)

It's the same, apart from the 2004+ CVPI which got a boost to 250 bhp due to a Marauder air box and zip tube. 2004 was the last year for the mechanical throttle linkage, before they switched to TBW in 2005.
Edit: I would recommend he goes for an '03+ PI. There are way too many changes under the skin.

I would have the Ford Dealer or a trusted mechanic put it on the rack and check everything out since these cars are driven very hard..The Highway Patrol cars are usually in much better shape then the local cars..
I know some people got former F.H.P. cars and they love them...Some people I know got some local cars from the Miami Beach P.D. and the Miami Dade P.D. and they needed allot of work.
He might get a good local car but its rare.

He does some car scrapping and one of his contacts put him onto these. The engines are actually okay, but the tranny's are pretty much shot. He was thinking of getting the cars, removing the engines and anything worthwhile, then parking them off to the side of our little country road - the speed limit is 25, with kids playing everywhere, but people routinely drive 50-60 through there. Having an X-police car sitting there MIGHT slow 'em down a little.

Hmmm...
Some of my friends told me that the reason modern Crown Vic cop car engines was because every cop car was built with dual exhausts, and many civilian cars were built with singles.

used to be on the line and they got a cool water to oil cooler ,screwed into the oil filter adapter and then the oil filter screwed into that.

The dual exhaust does give them a significant power boost over the LX models.

My 99 had dual exhausts [Performance Package] it gave the car an extra 15 H.P. as I recall...It also handled allot better then the ones without it.
Ford dropped the Performance Package for civilian use a few years ago...I thought that was a misstake cause it made the Crown Vic and Grand Marquis handle like a sports car...I miss it in my 05 Crown Vic.

The Miami Beach Police P.D. and the Monroe County Sheriff [Keyes] do that in certain places to slow people down...But after a short time the public who travel those roads daily catch on and go back to their old ways quickly.
CA police vehicles get all sorts of goodies added on (and things that are taken off, ahem, smog parts...) that are taken off, or re-installed, when they go to sell them. Sometimes, if you are a lucky one, you can get one that still has their special computer tune in them because it was missed or overlooked when they were going through them.
Not sure how it is in other states though.

The special computer tune is a myth. It's true that the engines idle a bit higher, and the transmission shift points are different, but the actual engine tune is the same.

+1 no difference in tune. none of the police cars here have anything special done to them. one of our departments only has 1 car with a limited slip. they opted for traction control instead.

I drove an LX model before I bought my P71. The LX handles like a boat, feels like you're riding on an ocean of waves. The P71 handles VERY well given its size and weight. The difference between the LX and the P71 (and the Performance package cars) is night and day.
I throw my P71 around corners like it's a much smaller and lighter car.

My Townie with PI suspension actually handles VERY well.
The base Vic/Townie/GM doesn't even have a rear sway-bar. They DO handle like boats. But the cars can be setup to handle quite well.

No difference in the engine itself from a P71 to a civilian model. The police cars have an oil cooler added in the lower radiator hose, and some of them have lifetime silicon hoses installed. Of the two you listed, the '03 would be my choice. It has a knock sensor to prevent pinging, and an improved suspension. As for things to look at for, the timing chain guides can be worn on cars with a lot of hours/miles, and the '03 cars had lots of issues with rear axle bearings.

The difference in handling and steering is also night and day, when comparing a pre-2003 to a 2003+ model.
