Re: 1996 LT-1 6speed questions
The "highway patrol" car is simply a Z28 without the badges - same engine, same programming, same trans, same rear axle ratio. Search on option "B4C". All M6 cars from 94-02 had 3.42:1 rear axle.
From the 4th Gen FAQ:
Q: What's included in the B4C police package?
A: According to "The Genuine Camaro White Book" by Michael Antonick, on a 93 Camaro, the B4C "special service" option included:
6 speed manual transmission
3.23:1 ratio limited slip rear axle (93 only... all other years 3.42 with the M6)
Single exhaust and converter with dual tail pipes
16 inch aluminum wheels
4 wheels disc brakes
124 amp alternator (140 amp for '94 and on)
150 mph speedometer
Engine oil cooler
The term "performance suspension" refers to the suspension, which normally comes on a Z28, as opposed to the suspension, which comes on the base non-Z28 Camaro or on the 1LE Z28. One other enticing thing is the package is cheaper than the regular Z28 options in order to give law enforcement and local government a break. Good luck trying to order one though. First, you have to find a dealer who will do a fleet order for you. The B4C is a "special services package" that is only orderable under a fleet number. It has no "stated" restrictions in the order book, but currently Chevy will not build one for a non-police department. And that means providing documentation indicating delivery to a police station.
What you need in the way of smog depends where you live, and what kind of emission checks you have. If they just plug into the computer and look for trouble codes, you can delete the AIR and EGR connections completely, and have the resulting codes "programmed out" as part of your mail-order tune. If you live somewhere that they rigidy enforce FEDERAL regulations, you may not be able to do much at all. In states like CA, you need a CARB-EO emissions authorization tag welded on to the headers by the manufacturer. The dual cats on your 96 will have to be kept i the stock locations, AIR and EGR must work.
In between, are locations that just run tailpipe tests, and don't care how you pass. You will need cats, but they won't care if you have relocated the cats, for example, to allow the installation of long-tube headers. AIR is only used to heat up the cats on cold start, to that's not an issue on a tailpipe test. EGR reduces NOx emissions, so if you delete that, you might have a problem passing a tailpipe test.
