Since Scott from Harms Auto posted in I'll show you his restoration on the carbs I bought from him. The date code is G7 and my build date is 4/15. Would these be correct?? It does not matter but I never did ask. Since I got them from Harms I had them totally disassembled and blueprinted and put back together. They were test run and performed flawlessly. I am going to race in the pure stock drags with this car. I did find out that stock 625 afb's only flow about 585 cfm each. LOL I don't know where you got these carbs from but they work very good.... I have had some real bad oem carbs in the past
