"We gotta get out while we’re young
`cause tramps like us, baby we were born to run"
(Springsteen)
In December 1966, Chevrolet quietly released one of the most famous options codes of all time, RPO Z-28. Unpublicized and unknown by most of the buying public, the only way someone could order the Z-28 package was to order a base Camaro with the Z-28 option, mandatory front disc brakes with power assist, and the Muncie 4-speed transmission. You could not order the SS package, automatic transmission, air conditioning, or the convertible. What you got was a unique 302 cid small block that was created by taking the 327 block and installing the short-stroke 283 crank. Specifically designed to compete in the SCCA's just introduced Trans Am racing series which placed a 305 cid limit on its entries, the Z-28 was available to the public solely to qualify the car for racing.
Advertised horsepower was listed at a modest 290bhp. Hook the Z-28 up to a dyno and it told a different story: 360-400 bhp. The Z-28 also came with a competition suspension, broad racing stripes on the hood and trunklid and could be combined with the RS option package. There was no Z-28 badging at all, lest it attract too much attention. The Z-28 proved to be difficult to launch on the street because its high revving engine was lethargic under 4000rpm and worked best when it was shifted at 7500rpm (!). Once it got going, the Z28 was tough to beat and boosted a 140mph top speed and numerous racing victories. Only 602 Z-28s were sold in 1967, making it a truly desirable collectable.
