Offy Intake question

I have done a few searches and have come up empty handed so if this is a repeat I am sorry. Is there somewhere I can get the casting years for Offy parts. I have an intake and i was trying to figure out when it was done. Thanks

 

I too wonder this. I have a SBC Offy intake but there is no marks on it other than OFFENHAUSER and 360 degree

 

Maybe Offenhauser can help you. If you had a picture, make of the engine and any part number that might be there, someone here might be able to narrow it down with Old catalogs.

 

Most of the time, on the bottom of the manifold there will be a casting date.
