    What code is on the ID decal on the front of the left valve cover ? I am having some made and need the correct 2 letter code. Is it the code in box 27 of the Build Sheet ? Scott

    Tim,

    Do you have that same chart for the big block cars that shows mine? ("PE")

    Thanks!

    Thanks, Tim!

    I really need to get my hands on an assembly manual.

    I notice there's no option for manual transmission w/out air conditioning, so I guess PE would have been the code for both.

    For 70, if you had a Stage 1 with a manual trans it didn't matter if you had AC or not because ALL Stage 1 cars came with the AC Pulleys on the Engine sub-assembly. They put the appropriate ac or non-ac parts on at final assembly, but the engine sub-assembly (as it left the engine plant) was the same.

    For 70, there were only 2 different Stage 1 engine sub assemblies, either manual or automatic.

    This was not the case for some other years.

    Brett,
    Yeah I hear ya.
    Some of the info I posted is NOT in the assembly manual. After you look at it for a while you will start to notice that Final Assembly, which is what the book was all about, did not install certain things.

    At that time you start understanding that certain parts came to final assembly as sub-assemblies that were already some what put together by the venders.................and if you look at different year manuals, you get to see where some of these sub-assemblies were removed and others added.

    The manuals only go so far, after that you need to "deduce" what was actually coming in and how they did it. You need to do the same thing when figuring out what a "base" car looked like. Then when you add the options you get a true picture of how it was delivered.
