The jets in a Quadrajet are .073 and the metering rods I have seen in rebuilts are 43M, 50M, and 52M. So if I get this Quadrajet rebuilt what metering rods do I get put into the .073 jets for good fuel effieciency. OR do the rods even have to be replaced? I'm thinking both the jets and rods are replaced in rebuilt carbs? Edlebrock's Rochester Quadrajet 1904 has the 50m rods in them.
