    Intake manifold

    # B12480203 spreadbore primary 1 7/16ths secondary2 1/4". Is this a BUICK intake manifold ? What year and motor(s). pulling my hair owt trying to find owt. Thanx in advance if you've helped. I kinda remembered someone telling me it was for the 430c.i. It weighs a ton.

    The intakes for the 400/430/455 we have on record are in the reference section under Buick Engine Identification.
    Here: https://www.teambuick.com/reference/..._big_block.php

    B12480203 does not show. Letter prefixes are not recorded, nor are suffixs (probably why yours show 8 numbers instead of 7). There is a 1243020 which is very close and if you misread the 3 for an 8 would match.

    Thank you for the info. Your the best. Trouble with the engine code, if I knew that I prob wouldn't've had to search, I think(?). It was given to me with no other info. Any knowledge of why they cast that anchor so heavy ? I'd have to use an engine hoist to set on w/engine in the bay.
