Are you planning on making this a show car? If so, swapping back to the original carb is understandable, and please post a picture of the car.
If not, why bother? The Edelbrock, unless there’s something wrong with it, probably offers better performance, mileage, and possibly better cold starts and driveability. Though I’d have to say that the Carter carb I had on my old New Yorker was flawless…
