I am in the process of just finishing installing a 261 into a 1950 1 ton pickup... I had asumed that a standard rochester air filter would work but the 261 specific rochester has a larger inlet flange

Did they make a oil filled air cleaner for these engines when used in trucks or are they the dry filter element type?

Anyone have an oil filled air cleaner specifically for a 261 rochester?
