Would this work on a N/A 13B by chance, or would it have to be a Weber 51 IDA carb to run right?

 

a 48 IDA is plenty big enough for most 13B's

 

K thanks, I'm deciding what I want to do... I thought I'd get rid of the 13B I had but now I'm going to be committed to swapping the 13B into my '71 Squareback like i was originally planning on. Now the question is should I swap it over to a 48IDF Carb or leave it EFI. (If I left it EFI I'd need a computer and an engine harness)

I'm basically looking at price wise, It would be easier and probably cheaper to keep the efi, but just in case I don't have the room for it I will need to get all the info for a carb setup.
