Because of its weight, I assumed the Holley NH carburetor was cast iron. Cleaned up, it appears to be something else. Anybody know what material was used?
Steve, will a magnet stick to it?
It looks like a cleaned up formerly rusty common old NH carburator.
It is cast iron.
it is cast iron that appears to have been "sleeping with the fishes"..not uncommon for t parts actually.
Here is what it will look like complete.
Good cast iron, when bead blasted, can look very nice & bright. Had a guy at a swap meet looking at a '29 Chev pressure plate that had been bead blasted the day before ask me why I'd painted it with aluminum paint. Took some talking to convince him about the glass bead treatment.
