People say that 40 Dels are the same as 44 IDF's and 45 Dels are equivalent to 48IDF's but that's because Del's from the factory usually have bigger venturis than the same size Webers. Put the same size venturis in them and they'll flow close to the same and make similar power.

That is partially true, the dellortos to come with bigger venturies to the same size as the Weber IDF carburetors and if you match that Venturi size to a dellorto it will flow close to the same but the dellorto will still flow more due to the fact of the casting of the upper aux venturie is less restrictive of air flow than the weber as is the dellorto throttle shaft.
