The cfm rating is from memory, so I could be wrong. The info on the air bleeds is something I found on a Ford message board.....don't have a link or even remember the name, sorry. There is lots of info on this carb on the internet. The 2100 was developed in the mid fifties and evolved into the 2150, it has quite a loyal following among 2 barrell enthusiasts. Your Jeep will run fine with the 2100. The improvements made to the 2150 were done strictly for driveability and ease of tuning issues, not power production.
