318 2bbl to 4bbl: Is it worth it this time?

Bear this in mind:
With the 2bbl, there is a chance that you have to have the throttle open more to get going away from the stoplight then you would with the 4bbl. I like the idea of the small 4bbl, and the 2176. I would make sure to have a fresh tune, and if you do not have a dwell tach, borrow or buy one and adjust the carb, via the air fuel mixture screws, for the highest vacuum/rpm possible, before adjusting the throttle screw. I would also check timing, because a little more advance could add some pep, and throttle response, requiring less actual throttle to get the vehicle moving, and ultimately better mileage.
