The Rochester 2G series is a wonderful series of carburetors. If you pick carburetors of the proper SIZE, and fabricate a good intake manifold they will work extremely well.

If you pick the incorrect sized carbs, or use a "M squared" manifold; you will probably be less than pleased.

Good carburetion is fuelish hot air
The most expensive carburetor is the wrong one you attempt to modify.
