The carb on there was hardly used and the 4160s are not bad carbs. Only rebuilding it for potential gasket leaks.
Once I get the car up and running and solve any radiator, cooling system, clutch, fuel pump (they get old), electrical glitches, new tires etc., I might consider a new carb. Regarding carbs (not fuel injection) Edelbrock's new redesigned version of the Holley looks pretty interesting. I think that tuning any fuel system seems to be much easier with a wide band 02?
