I have no clue as to what these are, they are Olds 10 bolt, they are stamped 1965 OLDS inside the cover.

Possibly MOON covers, if so they are pricey...

 

I've checked Cal Custom and Offy and can't find a match, I will look up some Moon's, thanks!

 

They may be Edelbrocks, those breathers could have been added on and the Edelbrock name milled off.

 

I think we have a winner, those are also pretty rare aren't they ?

 

edelbrocks...

some have the script some dont

i have some for a nail head and they say... 59 BUICK...no script

 

I have Edelbrocks from the early 70's and the fins are not so deep and they dont go all the way down the sides..... if they are Moons they were discontinued many years ago I would think.

 

Edelbrock made a couple different styles, The picture that oldcutlass posted is a very rare style, as a matter of fact I think those were only made in 65 or so, I have had several sets like you are talking about those were made later on!
