Hey slick - I just sold my "C6..." date coded Holley for $200 and that Dual Point dist. for another $200 - I guess it's more than you were going to give.
That along with my Sidewinder for $750 demonstrates that some of these "old parts" are worth something. My heads went for $2500 - much to my surprise. Ernie is right about proving authenticity on something like this - very few actually care that much and the carbs are going to be about $300-350 each to have professionally refurbished from Pony Restorers - the best around.
