both set ups can work flawlessly on a daily driver. It's about what you are personally looking for out of your project. Some 4bbl swap their 318's for performance. Some swap for looks. Some because grabbing that 600 carb was easy. One thing for sure, it's a relatively easy swap to do at any time.
Rookie question…will the same kickdown & stuff work from 2bbl to 4bbl? Is it just a matter of connections/brackets and depends on carb you get I’m guessing?
