the factory service manual had the jet sizes listed in it. This was for a 72 Dart and the Holley 1bbl in it used the same jets as the Holley 4bbl's. The FSM will also have a lot of other carb specs adn settings in it specificatlly for your application, rather than a more generic set from a one size fits all aftermarket manual.

Holley 553 is just a close tolerance hand selected #53 jet. But I wouldn't use 2210 specs on a 2245.
