Carb CFM recommendations

600 Edelbrock. One and done. But don't get the 1406. Get the 1405. The 1406 is the emissions carburetor calibrated for fuel mileage. The 1405 has an actual performance tune.

The 1405 is manual choke and the 1406 is electric choke. Beyond that they are essentially the same carb. I cannot use a manual choke carb.
