1952 Saratoga need help

Hi guys! First of all I know it’s the wrong forum but I also know it’s the best MoPar forum on the web so I’ll try anyways!

My father has just bought a 1952 Chrysler Saratoga with 331 Hemi

And since we got a 4-barrel intake manifold with the car but nu carburetor I started wondering if it’s possible to change to 4-barrel and still keep the fluid drive working since it gets electronic signals from both vacuum and mechanical linkage on the present 2-barrel.. Anyone got any ideas?

Second question - Is there a good way of converting the car to 12V from 6V and still keep all the original equipment working? The biggest hurdles would be the blower motor and transmission solenoids, right?

Best regards, Emil
