How do I choose a new carburetor?

How to Choose a Carburetor

1. Engine Size (c.i.d.) X Maximum rpm/3,456 = cfm at 100-percent Volumetric Efficiency (VE)
2. Example: 350 c.i.d. X 6,000 rpm = 2,100,000/3,456 = 608 cfm. Approximately 608 cfm would be required for this engine.
3. Street Legal Carburetor.
4. High Performance Street/Strip Carburetor.
5. Race-Only Carburetor.
