View Full Version : Engines Informations?

I know my 3400 is a LA1 but I read on here people talking about engines with the LXX number and letter designations. Some posted about a LQ1 and I have no idea what that is. Is there a list somewhere what engines are what, what they came out of, horsepower and whatever specs they are.

GM has RPO codes for every engine they've made. Engines always have an "L" in the beginning.

This gives a good overview of some of the changes in the GM 60 degree V6 family, but it doesn't give the engine code designations. Most that info is in other places on that site though.
Just for quick reference, the 3400 is LA1. LX9 is the 3500 that came right after it based on the same block. LQ1 was the DOHC 3.4L V6 produced from 1990-1998 for FWD applications.

I just asked Mr Google and they list all the numbers. My old brain isn't acting as fast as it used to.

Yeah, you can usually find some good info on wikipedia as well.
