Question about Holley/Proform main bodies?
If the main bodies are compatible from a 650 up to an 800DP carb for one main body. Does that mean a main body swap on a 650 will net an 800cfm carb in the end? What is the difference between the carbs to begin with, just the main body flow rates?

Does the Holley say 800 CFM? Proform says/said 750 CFM.
The universal Holley 650's and 750's used the same throttle body. The difference in flow capacity is the venturi size.
