I have a 1989 9C1 Police Caprice, and my main question is always: how to make it go faster and perform better. How fast is it? Well, not fast enough.

Here is what I have done: Rebuilt 700R4 trans, billet servo, shift kit.
Performance Distributor's cap, rotor, module, wires, platinum plugs.
Mobil 1 Syntec extended life oil. K&N oil filter, K&N air filter, and K&N chrome filter lid from Summit Racing. A Flow Cooler hi-perf water pump, also from Summit. Hotchkis springs dropped the stance down about 1.5" and Bilstein shocks. Also a complete Performance Suspension Technology front end kit and performance rear brake (drums) kit. I need to replace the tires, and I am considering a set of Yokohama Avid ST. P225 x 70 in front, and P255 x 70 in the rear. Rear tires, slightly wider and taller. I also have a Hypertech chip which I will install after I get the new tires. All you fellow gear-heads, any more ideas? I live in Illinois, and this car MUST pass their tough emissions test/scam every two years... I am building the car for performance, and better milage. The original style exhaust is still on the car, and I would like to get street legal headers ceramic coated wtih AIR and Oxygen sensors, a Random Technologies high-flow Catalytic Converter, and some type of dual exhaust set-up. Most realistically a Flow-Master one in two-out set up like I have seen on line for Firebirds and Camaros. Does anybody out there have any experience with this type of vehicle, and or set-up. So far I have built this car on a budget. I don't make a lot of dough, and money is always a factor. If you have ever owned or driven one of these vehicles, you know they are one of Chevy's greatest, but I know there is still a lot of untapped potential there still... Thanks. JC
