    I dont think it stands for anything. I think its just a code gm used to ID the motor.

    Don't know for sure. GM engines seem to all start with an "L" designation, so I can't even say the first letter stands for "longitudinal".

    GM transmission designations start with "T" or "L", for transverse or longitudinal, but that doesn't seem to apply the engines(of course transmissions are much more restricted with regards to their mounting orientation). I think it's just an internal designation for each unique engine configuration(intake, exhaust, displacement, etc.). I don't the "LT" stands for anything, either. Engine designations do get reused, e.g. LT1.

    off the internet:




    Best Answer: up until 1962 all chevrolet engine model,s were number,s only...the L designation started in 1963 with the L75,L76,& L84....that remained [ with some number change,s] until 1969 & even then the only exception was the ZL1 [ a very rare all aluminum block]. in 1970 they introduced the LT1 [ small block] & the LS5 & LS 7 big block,s...[ although it is said that no LS7 were produced that year] in any case the ,LT& ZR model,s were small block,s as where the the LS model,s were big block,s...the letter designation was simply an easier way to distinguish a small block from a big block...I hope this answers your question...good luck!
