I have some Holley 750 vac secondary carbs and was wondering how these work when converted to alcohol. (3310-2's) Or is this something not even worth trying?

If they were built by someone that knew what they were doing, use them for slick tracks/hard tires.

The vac secondary carb that i run was built by c&s specialties in st charles mo. The key to having one professionally built it adjustability, since the driver has essetially no control over the secondaries. They work very well as gene said on slick momentum type tracks. The downfall of them on tacky tracks is that the driver cannot get the car to turn with the motor if the car is tight.
