    was wondering why buick list the 246 stg 1 carb for both auto and manual trans cars when the other gm brands {olds/pont} list separate #s for there q jets? is the buick 246 exactly the same between auto/manual trans cars?

    thanks charlie,,,

    Buick does list a different carburetor for a 70, GS 455 number would end 243 GS 455 four-speed, Buick did not have a specific stage one carburetor for a four-speed Auto and manual are the same.

    It's a good question. All the other Buick engines in '70 have a specific 4BBL carb for 4-sp. vs. Auto. A 350 or 455 4-sp. carb, while not worth as much, are even harder to find than a Stage 1 as a result. I don't recall ever seeing the reasoning behind the Stage 1's but the configuration of the Stage 1 carb is more like a typical 4-sp. carb. Maybe someone on here knows (& maybe I've forgotten). Dennis Manner is the father of these engines and is still around and attends Buick meets. He'd probably be the one to ask.

    thanks guys, larry thank you for the spread sheet! the riv carb seems pretty much the same sans some vacuum brake stuff. i guess because of the more aggressive stg 1 cam?
