Q-Jet Question? Needles and Jets.

[veinbar]

I have a '75 and up Q-Jet w/o the computer controls. It has the jets and needles in it for a 307ci, but it's going on a 357ci. I need to change the jets and needles. It has an electric choke, but other than that, no wires. I know that the needle length in Q-Jets changed in '75, so the needles are not interchangable from the earlier style to the later style. Here is my question.

Are the needles and jets interchangable with the computer controlled Q-Jets? I did not find a carb like mine on a 350ci, but i found several later computer controlled models on 350s. They are seemingly identical, and I'm willing to bet that the needles and jets are all interchangable. I'm just not certain.

So... I know the needle lengths in Q-Jets change in '75, so does that make all Q-jets '75 and up interchangable?
