Still have the Holley 2bbl? list 4792? I have an AAR auto and for some reason it has a list 4791. Dated Mar 5, 1970. Not sure if it was from factory that way as car has been in family since early 80s and was (?) not molested then. I really am not too concerned about this but if I could find the correct list I may go for it. Not on this forum much so contact me @ [email protected].
