strange #3933163 intake
 

This intake is aluminum and has the part number and firing order like all the rest of the "163" intakes I have found but this one has no Winters Foundry Snowflake and has not been polished that I can tell. It also has A very small raised area(not A stamp) near the firing order that says "zeus" or something close to that. Can anyone explain the missing snowflake and the casted in letters to me. I failed to look at the dates underneath but will have the intake in the garage in the next few days and can look more closely. Thanks

Tommy

There is a Zeus aluminum foundry is Dudley in the West Midlands of Britain. Might have cast up some stuff for GM. You never know what GM was up to. Zeus has come up in a conversation last year and I think it was to do with GM intakes.
