1995 Chevrolet Caprice Classic - How The Law Won

Williams asked at just the right time. GM was in the process of moving from Chandler, Arizona, to a new proving grounds facility in Yuma, and was looking to offload tons of parts. "They had two LS6 engines and two 4L65E transmissions headed to the dumpster," Williams said. GM freshened the transmissions with some new and upgraded components, and Williams added a Comp Cams 224/224 roller before installing the LS6 in the Caprice. With the help of a Street & Performance installation kit, the engine and transmission went in easily. Not so easy was the process of merging the new wiring harness with the car's old one. The budget didn't allow for a trick adapter harness, so the two had to be spliced together manually.Although GM, Wal-Mart, and others donated parts and money for the car's completion, Williams still invested about $6,000 of his own money, of the $20,000 to 25,000 that it cost to build the car.

On his off-duty time, Williams takes the Caprice to a couple dozen events each year, including drag races, road course events at Phoenix International Raceway, and various open community events. "[The car] is better-received than I thought it would be," Williams said. "Both the old and young love it, and parents think it's an awesome thing.

"It really breaks down the barriers between racers and the police, who usually mix about as well as oil and water," Williams added. "Once the racers realize that I'm a gearhead like they are, I get that buy-in from them," he said, and they begin to appreciate the work Williams is doing to keep the streets safe and promote racing at the same time.
