    Ordinarily I'd whine about the Helms manuals, but they don't have one for my '74, as I discovered today trying to unfsck the mess left by a PO.

    The Chilton's for the Blazer is no help either... and the one for the pickup only lists them for '77-79, and says "Diagrams dipicted [sic] here are also representitive [sic] of the types of emission controls that can be found on engines used in the 1970-76 models."

    They're taken straight from the factory manuals, which prolly didn't print them until '77.

    I can scan these -- or my '77 factory manual -- but I'll be damned if they helped me (I have no EFE nor any of that other crazy stuff on my '74.)

    No diagram under the hood, huh?

    I don't know about my pcv or evap, but I know my vac advance runs straight to the front of the carb.



    *edit*
    Come to think of it, I think my pcv runs straight to the front of the carb as well /forums/images/graemlins/dunno.gif
