This is a  Buick 225  V6 factory single barrel intake manifold for 1964 - 1965 from my information. I believe this will also fit the earlier 198 V6 and the 225 GM V6 used by Olds in the 60s but I don't know for sure. Please be sure before bidding. I only guarantee it fits Buick 225 V6 for 64 - 65. 
 
This is the factory cast iron manifold. It could use some cleaning, but I believe the part is still perfectly serviceable. 
 
This casting has the part number B1361552-1M if I am reading it correctly.
 
Please check the number before bidding as I am not an expert, just going by my reference data.
 
I will ship this item for $ 30 to the east coast and $ 16 to the west coast, in the lower 48, actual charges elsewhere via Fedex ground.
 
Local PU in South Scottdale AZ.

I prefer cash with local pickup.
