I have 2 pairs of C5AF Holley carbs that I plan on selling soon, but unsure about their values. All 4 carbs are considered to be cores, not seized up or broken, but all have been sitting many years. One pair is C5AF-9510-BC & BD, dated 592, so likely from a 66 Fairlane R code car, the other pair are both stamped C5AF-9510-BD, with date code 373, so most likely were bought over the counter in the early 70s. I imagine the 592 date cars should be more valuable, since they have date codes for an early 66 Fairlane, rather than the 1973 dates of the 2nd set. I finally realized that I will probably never own a real 427 car that these carbs would belong on, so I figure I should sell them to somebody that can make good use of them, and use the $$$ to buy parts I am more likely to make use of.
