I have a '69 427/390 auto. Correct carb is the #7029204. I'm currently running a remanufactured Edelbrock from summit racing (SUM-210210) until I get the $'s to locate a correct unit. The Summit rebuilt unit has 0.069 main jet; 36B primary rod and DR secondary rod. On acceleration I get a hesitation.
According to this article I found: http://www.corvettefaq.com/c3/QJetTuningPaper.doc
The original set up should be a 0.071 main jet, 0.047 main rod, GM #7036019 spring and AX secondary rod.
Any idea where I find these parts and does this look like a good starting point?
