Hi everyone. I hope someone can help me identify an Intake Manifold I got in a trade over 30 years ago. I have had it my garage long enough and I need to identify it so I can post in the classifieds to hopefully sell it. So maybe some one could also give me an idea of worth that would help a lot too. The intake is aluminum and I assume it is factory because of the Winters snowflake. The part number is 406114 and the build date on the back says 8-18-69 0r 8-19-69. It also says Oldsmobile W-350 on it. I know the person I got it from many years ago said it came from a 1970 Oldsmobile with dual snorkel air induction. I will attach some photos and if I need some more to help let me know. It has been out of circulation since at least 1982 when I got in trade for a set of aluminum Edelbrock valve covers. Condition is great with no cracks or gouges in the mating surfaces. Thanks for any help you can give.

Welcome... X2 on the 1970 W31 350 engine intake...

 

Thank You for the identification. I did some google searches on W-31 and found out quite a lot of info. I still could not fine anywhere that would give me an idea of value. My plans are to post it here under the classifieds and if that does not work for me I am going to try E-bay. I just do not know where to start on a price that would get me the most without giving someone else a bad deal. Anyone want to give this one a stab? Thanks for the warm welcome.

 

heres a couple data points disclaimer: IDK anything about the value of these
