    LK is the production plant and 0720 is the 72 day of 1970 when carb was made.

    Thanks for the info.

    Do you by chance no what plant LK is?
    Is that flint. Since all Stage 1 cars were built there in 70?

    Thanks

    Rochester made carbs for all GM models, not just Buick.

    I believe the LK was to signify a factory issue Stage1 carb, as opposed to a replacement which would have the same part number, but different 2 character code (in addition to the date code). Other 1970 Buick carbs would have different letters.

    Usually, each carb part # would have a unique 2-letter code to go along with it.
