I use the Q-jet carbs. They have great driveability & good gas mileage. You can pick them up cheap at swap meets or pull your own parts type salvage yards. If you can o-haul it yourself you can save a lot of money. Try to find one with minimal wear on the throttle shaft. I always use one with the round built in choke & change to electric choke if it is not already. Then you don't have to be concerned about matching up to the manifold. Don't get one with electronic controls. You can get HEI units cheap & o-haul them yourself.
