Classic over carburetion problem?

For a 4 speed car with tall gears I’d agree that the double pumper is a better carb choice but for an auto with a low stall and 3:55s you’ll probably like the vacuum sec carb better. Either way the amount of tuning you’ll NEED to do is about the same. A little more with the DP. For a new hot rodder with limited experience you’ll be better off learning on the VS carb. Don’t just throw parts at a problem to fix it. Diagnose, adjust, test. Then if you need parts replace them.
