Not really. The numbers are mostly irrelevant unless you are looking to be "numbers matching" in a restoration. You want the Chevy fuel inlet (side instead of front) and have the proper advance and choke for your application. As long as it's a 170 series carb that doesn't have the feed back plug in the top and is not a computer controlled Q-Jet you'll be set.
Write down the rod/jet and rod/hanger combinations along with your model number if you don't mind, I'd like to have them for my records.
If you need/want some help rebuilding it, give me a shout.
