    Thanks for adding to the evidence 67Resto and COPO, much appreciated!
    Not sure if this will ever change any of the info on the websites, but that's my goal!

    My 1978 Z28 with an auto trans has CHT as the engine code. It is a Van Nuys built car with California emissions.

    Thanks for the info Z28SSRS! This is the quote from Post 88 of this thread:

    "Just an observation, the CHT code appears to be automatics with California emissions and the CHC automatics with Federal emissions."

    Nice automatic '78 Z on ebay today, they posted the build sheet as well. Hard to make out but believe it to be CHC engine code suffix.
