Can someone explain the differences between the different series of these carbs? In particular, are the cast bodies interchangeable? Even more specifically, how does the body of a 40 DFI/2 differ from that of a 40 DFI/5, if at all?
Thanks,
George

Re: 40 DFI carbs
On DFI carburetors, the chokes (venturis) are not removable, they are cast into the carb body. The DFI2 has 28 mm chokes and the DFI5 has 32mm chokes. One is for 330's and one is for 365"s.
