Hi Cameron(and anyone else who may have the info) The numbers on my carbs are: 9635S 9635SA 9400S 7900S Any help? Both pairs were supposed to be matched carbs. I was sold the bottom two numbers as a rebuilt pair of 400 cfm carbs. I was planning on using them on a stock 383. The top two were sold to me a rebuildable pair of 650 cfm carbs. I'm going to use them on a warmed up 440.
