I'm kinda having a hard time figuring all this out. what are the pros and cons or just the best for my application? I am running 425 cid nailhead in a 1958 Buick. My questions are: What brand carb should I use? (easy to tune and adjust) What CFM's, been told 750? (street drivable, not a race car, not a daily driver) Choke (electric or manual) vacuum ? bolt pattern? part numbers I want something simple, affordable, and reliable Thanks in advance......
