Its the 3 digit code gm uses to identify the engine family. They have been doing it for years.

More specifically, its the RPO code. Look in your glovebox and it will be listed.

Not sure how they came up with the RPO engine codes but - - - RPO stands for Regular Production Option. Manufacturing site: Moraine, Ohio

01-04 LB7 Injectors housed inside valve covers and no EGR, with the exception of California models
________________________________________
04-06 LLY Introduction of Garrett VGT turbo and EGR
________________________________________
06-07 LBZ Revised piston design lowered compression ratio to 16.8:1 from 17.5:1, a stronger block debuted, and a 32-bit ECU was introduced
________________________________________
07-10 LMM Introduction of DPF and exhaust after treatment
________________________________________
2011 LML Extra fuel injector placed behind turbo, urea injection, and dual-loop EGR system
________________________________________
2011 LGH Detuned version for 2500 and 3500 vans and will use GM's 6L90 six-speed transmission instead of the Allison 1000

GM has been using the 3 letter designation for years. All engine in GM vehicles will begin with the letter "L". This applies to all gas and diesel engines. The same is true for all transmissions, the only difference is they start with a "M". The "L" designation for engines is piece of history for GM. On rare occasions, they reuse the RPO, but it is very rare. A lot of GM vehicles have been identified over the years by RPO. Some of the more famous ones in my opinion are Z71 - used on 4x4 trucks, ZR1 - used on HP Corvettes, Z28 - used on Camaro's. There are plenty more. Hope that helps.

Oh yeah.
Less than 2 dozen made in '67, before the body change to stingray in '68.

L88 Coupe

Got to drive a '68 years ago; sent as a runner to go pick up the Boss' wife's car from the shop. I was the only one in the office at the time that knew how to drive a stick and No one bothered to mention beforehand, anything about this car. Just a raised eyebrow and half a grin, "Don't mess it up, I wouldn't want her mad at me if I was you!" I just thought it was another Red 'vette with a 350 and loud exhaust....not a 600hp beast with a wicked clutch. Scary.
