47-55.1 Carb Question - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Dachshund · 03-09-2019, 11:02 PM

How do I find out what carb I have? There are ZERO markings or tabs on this one, other than "Rochester". It's a single barrel. and sitting on a 235. I'd like to rebuild this one (been sitting for 20 years...), instead of replacing it. This is also not the original carb. The only thing on it is a sticker that reads "rebuilt by Holley", with the numbers: 7073aa, and 2p04-991640. Any ideas?

Can you post some good quality photos of it? Well lit and decent resolution from both sides? Someone should be able to ID it from that.
