    Can anybody help me in finding the correct gap for my Chevy Suburban build 1979 with a 454 CUI motor?
    Have a manual but even so can't find it.
    Have the AC Delco sparkplugs type R45-TS.
    Many thanks

    If the engine is what came in the truck, and the sticker's still there, there should be an emissions sticker on the radiator core support that has emissions, timing, and spark plug gap info on it.
