Re: 1958 Packard ( Carb Change)

I have a 1981 Dodge pickup with a 318 engine that originally had a nightmare emissions 2 bbl carburetor. Someone added an adapter plate and installed an Edelbrock 600 CFM 4 bbl carburetor with an electric choke. It works pretty well.

A 500 CFM would would work better on the stock 318.

Of course, the original breather and carburetor linkage no longer fit, and I doubt if the performance potential of the 4 bbl is fully realized. It does start, run, and idle well, and the choke works well.

I believe the power supply for the choke is connected to the accessory circuit.

I think that Edelrock offers a 2 bbl carburetor that would probably be a better choice to replace a 2bbl.

Rebuilding the original equipment is the best choice, in my opinion.
