I'm trying to identify what Holly carb is on my 70 Chevelle. The numbers stamped on the horn are 80458 and 084. Can't find any information on Holley site. Am I looking in the wrong place for identification numbers on the carb? Thanks Tom

Are these numbers on the front/driver-side part of the choke shroud?

Catch me if you can:
Yes they are Tom

I can't find anything on that number in our database, I may be able to help if you can describe the carb a bit more and send a few pictures...

Not sure how to send pictures in this forum. Can you email me at ttripoli@twcny.rr.com and i'll send photos. Thanks Tom
