Ironhorse: 9625 is a Carter AFB number. I have a Carter AFB 9625A on my V8 350 in a '71 GMC Jimmy [k/5]. I tune it as an Edelbrock 1405 [manual choke]. I always thought it flowed 600 CFM, but there's no way to measure at this end. Carter designed and produced the AFB, then got bought out by Federal Mogul, who continued the "AFB Performance Series" carbs. The same [Weber?] plant was making the same carb for both FM (dba ''Carter'') and Edelbrock. The "Performer" Eddies were shinier and retailed higher for the same carb. Eventually FM dropped out of the carb line, leaving Edselbrock as the only game in town.
About 10 years ago, I put a Holley fuel pressure regulator inline to my AFB on the Jimmy, as advised by the many experts on this board. I wasn't passing AZ emissions, and after trying everything myself, got hold of a pro mechanic. First thing he did was tell me to lose the regulator. I still have it -- in the parts drawer.
Phenolic spacer is a must. I have a 1/2" tall aluminum Offy Squarebore/Spreadbore adapter on the bottom, over my Wieand 8004 intake, and a 1/2'' phenolic 4-hole spacer directly under the 9625A.
