I've been debating that very same issue and I've read a lot about it. Here my take on the issue. If you have the money go for the fuel injection if not go for the carb. Simple as that, fuel injection are way better than a carb in every single way. Carbs have a lot of limitation. If this car is going to be a daily driver, you might make it up in all the money you will save from gas since fuel injectors get about 5 percent better gas mileage. Have you looked at Holley lower end fuel injector? You might also look at gm tpi .
