I think a vented cap is a necessity for a car with a carburetor. How do I know? My vented cap got plugged up and it built up enough pressure in the tank to push fuel past the needle valve in a Holley double pumper, flooding the engine routinely when it was shut off during a warm autocross event last year. Getting it started again was a bit dicey, and was definitely not environmentally friendly! Once I figured out the issue and cleared the vent, everything was fine.
