Look for earlier 2Gs because you will have more tune-ability.

SUMMARY
The discussion focuses on optimizing intake runner design for a 2-barrel intake system, specifically for a Ford Y-block 292 engine. Participants emphasize that smaller intake runners can increase air velocity, which is beneficial for torque, especially in engines designed for low-end power. The consensus is to avoid oversized runners and instead focus on efficient porting techniques, such as smoothing and blending, to enhance airflow without compromising velocity. Additionally, the importance of carburetor sizing is highlighted, with recommendations for using 245 to 351 CFM carbs for optimal performance.
PREREQUISITES- Understanding of intake manifold design principles
- Familiarity with carburetor sizing and airflow dynamics
- Knowledge of porting techniques for engine optimization
- Experience with Ford Y-block engine specifications
- Research "Ford Y-block intake manifold design" for specific applications.
- Learn about "carburetor flow ratings" and how they differ between 2-barrel and 4-barrel systems.
- Explore "porting techniques for increased airflow" to enhance engine performance.
- Investigate "mini-plenum intake designs" and their impact on torque and horsepower.
Engine builders, automotive enthusiasts, and performance tuners looking to optimize intake systems for classic Ford engines, particularly those interested in enhancing torque and efficiency in Y-block configurations.

you need to get around more.
rochester doesn't sound too good.
sound expensive.
these Autolite 2100's are all over and
reasonable.
plus they're like working on half a holley.
gotta keep things simple to get the car to go sideways on demand.
Have A Nice Day!

Yeah, all a 4V carb is just two 2V carbs. With all the circle track 'bomber' divisions or of the like, the 2G or 2GC are mandatory (maybe more if Fomoco and Mopar can run) unless the Holley 4211 is allowed. I have quite a few for my sisters race car that I got for close to zero. I have never played with Autolites, I know they are pretty plain looking compared to a Holley.
If you ever need to a 2V carb, check the local race track (mostly oval I am not sure if drag strips have a 2V classes) to see if they require a 2V carburetor to be ran in one of the classes, you could score a couple for a decent price from a racer. The hot rodding scene might be a few bucks higher if you are looking for the factory carbs of any type.
