Re: 1938 Packard Six smoke and strong smell of gas coming from exhaust

White smoke is generally hot water vapor (steam) and suggestive of a blown headgasket or other condition allowing coolant into the combustion chamber. That doesn't necessarily explain your observation of strong gasoline odors but if for no other reason than to discount it, I'd check for coolant in the oil and loss of coolant. And perhaps a compression test.

Are you sure your choke valve is functioning? Assuming the choke is open and the air filter is clean and unobstructed, I'd suspect a faulty carburetor rebuild as a leading candidate.
