How do you identify a real 9c1 ?

That is news to me. Everything I've read, including Chevrolet Police Cars and www.9c1.com, state that 5.7L was not available except for police, law enforcement, and firefighting purposes from 1989 to 1993. Are you sure your LTZ was produced as a police car?

No my LTZ wasn't produced as a police car (9c1), it was AS CLOSE as you could get to buying a police car (9C1), brand new that is, without waiting for dealerships to finally notify you of an overstock of 9c1's not sold to law enforcement.

LTZ was an optional package add on to the 1993 Caprice LS that almost mimicked the 9c1 to perfection.

Here is a section of 9c1.com that provides ALL the motors available through the years 91-96 and ALL models....http://www.9c1.com/technical/engineapps.htm....Note the 1993 LTZ Optional package with the LO5 motor.

I hope this clears up the confusion.

Intresting. Did not know about that, but it appears it was only offered one year (1993). The next year (1994) would see release of LT1 and the Impala SS. Its odd that they paired your larger L05 (compared to L03) with the older 3.08 final ratio as opposed to the 3.42 final ratio popular in 9c1 from 1989 to 1993. Guess that means you might get a reduction in torque at the wheels but higher top speed.

So, except for that odd ball 1993 model and some of the station wagon models (1992-1993), the 5.7L VIN 7 was not offered outside for police, law enforcement, and firefighting use from 1989 to 1993.

You are correct sir ..........also having the 3.08 rear end is great for top end but off the line its pretty quick also but not as peppy as the 3.42 gear. I topped out my LTZ at 132MPH one boring night...full WOT, rpm's maxed at redline and was in shock at how everything turns into a blurrr after 100MPH

Pat is right, the 9C1 and Impalas will cost you big bucks to upkeep, only maniacs like us still have it. Thats why they were discontinued by GM quickly because they knew what shoddy job they did. For more information on the subject read about the history of the Arlington, TX factory where they were all made. We all should get unite, hire a law-firm to have GM to cover repair-expenses. These cars obviously have never met quality requirements.
