I ran a 4 barrel on my old 194 Nova some years back really woke up that little car. Don't have info on the carb was one loaned to me from a friends carb collection. This was using the OFFY intake bolted to the stock exhaust manifold.
Cable Lokar type throttle would probably be the way to go.

My friend runs an Edelbrock right out of the box on a Clifford intake, runs super on his 235.
