Edelbrock O4B Dual plane intake manifold, I think it’s for the 455. Has center of plenum trimmed down, and minor polish to carb area.. In the Buick world the B4B is kinda special, I don’t know much about Oldsmobile’s... Rare??
$275 Shipped to lower 48, local pick up available in San Diego or LA with price adjustment...

Wow I remember having a O4B manifold back in the day and I used a holley because the quadrajet wouldn't work, This one is for a quadrajet, Maybe they made 2 different types?? Good luck with the sale!

 

Yes they did make two maybe more. Look on the bottom for cracks as most do crack. I have one that is cracked but welded up should be fine. Not 4 SALE
