How do I choose a carburetor?
How to Choose a Carburetor
- Engine Size (c.i.d.) X Maximum rpm/3,456 = cfm at 100-percent Volumetric Efficiency (VE)
- 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.
- Street Legal Carburetor.

When there’s too much dirt in the carburetor, the required combination of air and fuel can’t travel through the passage to the engine, causing a turn over, but no catch or actual start. It’s running lean. An engine “runs lean” when the balance of fuel and air gets thrown off.
Which is better EFI or carburetor?
Warren Johnson: Properly tuned, carburetors make more peak power than EFI in a Pro Stock engine. EFI performs well over 2,000 rpm or more. On average, if optimized, both systems perform about the same as far as how fast you get down the track. However, the EFI system is much easier to tune than a carburetor.
