Z28, WS6, LS1, etc.
All are RPOs (Regular Production Order/Options) found on the SPID (Service Parts Identification) sticker. They are just codes, not acronyms.

Just like the rumors about what ZR1 "stood" for.
Again, these codes are NOT acronyms, they are just codes.

The Z28 RPO was originally for the 290 HP 302 V8 built for SCCA Trans Am Racing series to fit under the 5.0 litre limit.
The 302 is a 327 Block with a Steel 283 Crank, Pink Rods, 11:1 pistons, Fuelie 327 Heads, and solid lifter Duntov cam.
This engine option required a mandatory 4spd manual trans and standard 3.73 or lower optional gears. Also included special cooling and handling packages.

i dont think the numbers actually stand for anything in particular today, just marketing, something to brand on something, i mean look at SS, it has really gotten watered down, SS don't mean nothing anymore. look at dodge with HEMI, or the names charger, and challenger. its all marketing bs to make people but cars. period. it all used to mean something.....ah how times change.
