1982 was the first year of the third-generation F-body Camaro and the first time the Camaro returned to the Indy 500 Pace Car role since 1969. Chevrolet built a commemorative Z28 edition: silver lower body, blue upper body, blue-and-red Pace Car graphics down the rocker panels, blue cloth interior with red piping, and the new-for-'82 LU5 Cross-Fire 305 cubic-inch V8 — twin throttle-body fuel injection, 165 horsepower in '82 trim.
Y86 was the SPID code; the cars are also identifiable by VIN (8th char H = LU5 Cross-Fire). About 6,360 built — well above the 1,500 typical Indy Pace Car homologation minimum, since the package was sold as a regular dealer-orderable option through the model year, not just to commemoration buyers.
Y86 is a frequent target of cosmetic clones — applying Pace Car decals + repainting a regular silver Z28 is straightforward, and the LU5 engine swap is rare. The SPID label is the load-bearing identification: a real Y86 carries Y86 + LU5 (or the cross-checked VIN engine letter H) + the documented 1982 production-line build sheet if one survives.
