I have 2 of what I think are the "big" Rochester carbs. How would I determine if they are. Is it the size of the ventury or the size of the throttle plates?

The big rochester has 1 3/8 inch venturi. Most of the newer 2G carbs have 1 11/16 throttle bores, but have the smaller venturi. I've found several that had 1 3/16 venturi. You want the 1 3/8.
