    Intake manifold question

    Hi,

    Had a quick search before posting this and all I can find was if a ls1 manifold has this kind of pattern it's not an ls6? (Refer pic) Even though it has a flat bottom..... Is off a 2001-2002 Aussie built sedan VX Commodore (I think it's a chev lumina in the US or maybe a Pontiac).



    Thanks in advance.

    Cheers Simon.

    Got a part number from the guy and googled it. Looks like its actually a L76 rectangle port manifold? P/N 12590124. Any good for a ls1. I'm thinking no?

    It will not mate up to the cathedral intake ports on your stock LS1 style heads.
