An article in January 1972 Popular Hot Rodding on an 11 second 66 GTO shows the guy estimated about 1200 cfm for a set of hogged out 66 carbs. A picture shows heavy work on the tops of them. Seems like I read an article several years ago about a national record holder stock 68 Firebird campaigner named Jim Mino from Pennsylvania got about 1000 cfm out of a set of tripowers that he had done extensive work on. I seem to recall he had measured flows. ( I've got both these articles somewhere.) I also recall he had a bunch of tripower stuff for sale in Smoke Signals a couple of years ago.
