How do they name an engine??

Like, LS1, LT1, LS6, LB4, LO3?

And how come my thirdgen camaro's engines anrt listed by its "letter name" like the 4th gens?

If you know how they name the engines, is there a way to predict what the next engine will be called?

Is the name just the REPO code and nothing special?

It's just the RPO code and does not really matter.

All GM engines start with L, every Gen has it. Its the RPO/engine code.

In some cases they do pick a specific code, though... such as LT1, LS6, etc...

I'm talking the modern day ones anyway... to link them to legendary powerplants from the past.

To be honest, I think it'd be better to give them a new RPO and keep things less confusing. ;)

Ya gotta admit---L69 :D is the best engine RPO!

I've always found it amusing that out of all the auto manufacturers in the world, pretty much only GM's engines are widely known by their internal designations. Cruise any car-related message board on the internet (American, European, Japanese) and everyone will know what an LS1 or LT1 is. But how many know the codes for Hondas, Fords, etc. unless they actually own one? Even the car mags throw around "LS1" like it's common knowledge.

I agree with the 2nd half of this quote the best, considering the mighty LQ9 (Vortec 6.0 V8) used to be the Iron Duke's code (1xTBI 2.5 L4; 90hp) back in '82 :cool:

Their choice for engine RPO's seems to have no rhyme or reason except in rare cases. The H.O. 305 in '83 called L69 was named that way just because it sounded provocative. This particular one has been documented. :)
