Difference in carbs?
I recently swapped the carb on my 351w in my ltd with one off of a 302 f150. I'm wondering if there is a difference in CFM between the two as I now have a hesitation just off of idle.

There will probably be a difference in cfm, the 302 carb may be pretty small, depending on what year it's off of. What's the number cast into the side of the fuel bowl on the carbs? (something like 1.03, 1.21 etc.)

Jared, I found two numbers on the carbs, 1.21 on both which is cast into the side of the bowl. The other numbers are a 7 on the new one which is a non cali emissions carb, and a 14 on the one that was in the car which has cali emissions. The 7 and the 14 are stamped into the top of the carb over the fuel bowl.
