...I remember the commit that was said about the Crysler 440+6 that were rated something like 1300cfm.when i was researching the carb for my engine Holley had the nice little crab recommended deal (can't remember the name of it) on their site where it depends on the use of the car, they would recommend a cfm for you....it came handy for me.
2bbl carbs have a different rating system. 440+6 rating in 4 bbl terms is around 900 cfm not 1350. The 1350 sounds cool but it isn't the same as a 1350 four barrel carb. Lots of people have been confused about this since forever.
