Another Cam and Jetting question for IDAs

[invitation]

The Weber 48 IDA has been used for decades by VW enthusiasts whose goal it is to squeeze every ounce of performance out of their engine. Problem is, production of these coveted Webers was halted many years ago. These excellent carburetors in decent condition have become rather scarce! Typically VW motorheads (as we affectionately like to call VW performance engine fanatics) have to resort to scrounging the swap meets to find a pair of 48's and even then, they may not be lucky enough to find a pair but have to acquire them one at a time. But if you are lucky enough to acquire a set in usable condition, and you are willing put the time, money and energy into rebuilding and tuning them, you WILL be rewarded. The Weber IDA's sheer size will likely result in gasps of awe and astonishment from those that have never seen them before!
