    With all the recent cartalk, thought I'd ask a question everyone is wondering...

    What are the modifications to a factory model that make a "police interceptor" ?

    One of the admins that worked for me a few years back was an ex-city cop. He thought the only mods to the Crown Vic was the steering so they could track easier in reverse.

    What do you think ?

    I think the steering and suspension get strengthened a bit. I'm pretty sure the '94 Impala was based on the police variant of the Caprice and it's major difference was in the suspension. Pretty much everything else was cosmetic.

    The Ford police interceptor has better suspension, Z rated tires, better brakes, and a much better transmission.

    I could've sworn the cooling system also had some mods, such as a hi-po radiator and heavier-duty water pump...

    Glass on all windows is designed as bulletproof in newer models. (good friend is officer) otherwise, pretty standard. In fact, many are in semi-bad service.

    Meanwhile, HiWay Patrol have new vehicles.. they are driving Porsches at the moment around these parts [​IMG] I'd love to get the specs on those!

    You are kidding, right? [​IMG]

    The CHP (California Highway Patrol) has BMW motorcycles....and I am waiting to see what they will replaced their Z28 Cameros and Mustangs with.

    As an owner of a 1995 Chevy Caprice 9C1, I can fill you in on the upgrades the Police model receives over the civilian model:

    Upgraded HD perimeter frame
    3.23 Rear end gears
    Police Pursuit suspension (shocks springs stabilizer bars body bushings)
    Front and rear disc brakes
    HD Cooling Package(radiator, engine oil cooler, tranny cooler)
    Lifetime silicone hoses
    HD 140 amp alternator
    Special Calibrates TRansmission (use O/D for pursuit)
    HD wiring/Grounding package for added electronics/lights
    15x7 HD Wheels
    Special Balanced Driveshaft
    A/C wide open throttle cutoff (shuts off AC when throttle is opened all the way-keeps AC from robbing hp from engine)
    AC head pressure relief (helps prevent damage in high speed pursuit)
    Certified digital spedometer
    Electronic trunk opener
    HotMelt corrosion pads
    HD seats with anti stab plates (thick steel plate built into seat back)
    Cars could be ordered with either the L99 (4.3L) or LT1 (5.7L) motors...

    The Impala SS (94-96) was based on many of these special order options...

    They said the sales weren't enough to justify keep building the B-body (Impala, Caprice, and a Buick) and converted the factory to make trucks and SUVs. It's sad, really sad. At the time I believe that was GMs last RWD sedan.

    That is correct. The Arlington TX plant was retooled for production of the upcoming SUV line. The Caprice/Impala was the last RWD sedan GM produced. The Firebird/Camaro has also since gone extinct as well. That has left [email protected] the singular supplier of full size RWD sedans for fleet use since 1996.

    MANY police officers my local B-Body club has as members cherish the memories of their Caprice Cruisers. They say the Crown Vics just don't match up to the GM LT1 (350cu in) power and handling. Most of our organization have in fact purchased the Chevy 9C1's as cheaper alternatives to the pricier Impala SS. All the same toys with less that half the cost.
    Of course I am a GM fan...you will find an equally vociferous fan base for the CVPI elsewhere on the net as well. But for the money my vote went to the Caprice. Whats better than a big 4200 lb. four door sedan for a family vehicle that also happens to sport a 260 hp Vette motor!

    The Impala SS had a 260HP 5.7 Liter LT1. I believe there were some differences between the Vette and the Impala's versions. I think the Impala had iron heads but the Vette had aluminum. I could be wrong. I don't know about the 4 bolt blocks, I've never heard that term before.

    Not at all kidding. For the stretch from Topeka, KS to Colorado, Highway Patrol are currently using a combination of Porsche and Corvettes. For whatever reasons. The stretch of hiway there is very desolate, so *shrug* but I've seen speeding tickets on I70 go to court in Riley County for outrageous numbers (ie, 130 in a 75)

    Keith,

    4 Bolt refers to the number of bolts securing the main caps
    which in turn keep the crankshaft in it's journals. 4 bolt
    mains support more horsepower and generally speaking 4 bolt
    blocks are usually higher nikel content than non 4 bolt
    which also adds strength.

    The LS1's on the other hand are all 6 bolt mains (like the
    old Chrysler Hemi's)

    I remember a police officer friend saying he liked the Caprices. One of the things he really liked was they disabled the ABS, so it was fun locking up the brakes on turns.
