Weber Vs Dellorto?, Good, Bad or Ugly Options

[Levi]

I'm trying to decide which carbs to use on my 74 2.0L.
It now has duel Dellorto DRLA36's and my 73 1.7 parts car has duel Weber 40 IDF-19's
Does anyone have experience with these carbs?
which ones would give me the best drivability, performance,and fuel economy

Will the weber's bolt to the 2.0L Dellorto intake runners??

Over the years I have developed a love for both of these carbs since they were the best for their era (back in the stone ages fuel injection was the pits; mechanical and not very adaptive for the cost).. I have run delordos and webers on alfa romeos, lotus, and porsche. Of the two I favor the Delortos since they have a three stage progression state per carb whereas the webers appear to have a two stage.

Tuning is about the same with the same difficulties; parts are available from Europe usually from the same sourcing. Parts can also be sourced from other type cars such as Lotus without any problems.

Performance if tuned right and maintained are about the same although I give preference to the Delortos. I have not had any problems with either carbs. When I run carbs I like to set the carb to the cams and porting thus matching everything top end.

Pricing could play an important part in your decision---thus what is available in the best possible condition and what it is tuned specifically for. Linkage, intakes etc usually match and can be used with whatever one you choose.


You asked for favorites: I place originality prime when I am redoing a car; thus, if the car came with webers originally, I would use webers. Not because they are any better or worse that Delortos, but because they were original equipment. Other than that I would consider either one depending configuration, price, condition, source, etc. Considering these elements, I would use the one I get the best value.

Another way to look at it is this way: the weber was developed first; the delorto came next making improvements such as the three stage; next came pmo making more improvements. It boils down at this stage to value and cost; webers and delortos cost about the same; this depends on what configuration you are using.

Hope this helps you out
