You listed the wrong carb, look up a 500 CFM AFB (performer series).

"Comes with: Metering Jets - Primary .086, Secondary .095; Metering Rods - .065 x .052; Step-Up Spring - orange (5" Hg)"

This is incorrect, I spent hours last night chasing my tail due to it.


The listing I posted is for the dual quad calibrations, if you aren't using them in that configuration, my bad. The performer and thunder avs carbs show the same single quad calibrations. In the Edelbrock carbs they are only different in the secondary actuation. That is not the case in the original AFB/AVS carbs. I found this out the hard way. Anyway, good luck with your project.
