Good morning. Will running a 6 pack set up on a mildly built 340 have a differnce over a 650 4bbl? Automatic transmission. Thank you in advance

It will have a big difference on the "wow" factor when you open your hood.
If you mean performance wise, need the rest of the build, and what 650/intake you have now.
