In December 1966, Chevrolet released the first generation of the Camaro that was one of the most popular choice code of all time, Z-28 option. Unpublicized and unknown by most people buy (and most Chevrolet sales person in this case) and not mentioned in sales literature, the way a person can only be ordered Z-28 package was to order a basic Camaro Z-28 option, front disc brakes required by power assist, and Muncie 4-speed transmission. You can not order the SS package, automatic transmission, air conditioning, or conversion. What you get is a unique small-block 302 cid (Non-California emissions car labeled MO while California emission engines labeled MP) which was created by taking the 327 block and put a short stroke 283 crank. Designed specifically to compete in the Club of America Trans Am racing that puts limits on the input of his 305 cid, Z-28 is available to the public just to qualify for racing cars.
