The 830 is small so in that case I would say the 6 pac but I hate running multiple carbs... I would go with a 1050 dom... JMO ![](/ubbthreads/images/graemlins/wave.gif)

Mr P. Body is right about the 830 on your combo. The six pack flows about 950-970cfm at best (measured as a large cap 4bbl), which is great but not optimal for you combo. The 1050cfm carb would put you there. ![](/ubbthreads/images/graemlins/thumbs.gif) The 830 would not be bad, but you may not pull the numbers you want with that carb. ![](/ubbthreads/images/graemlins/2245452-furysmiley.gif)

I have dyno tested several stock type six pak set ups and a bunch of different single four barrel intakes and carbs, 600 to 1050 CFM Dominator. All of the Mopar V8 I have tested and raced have made more power and torque with more CFM than smaller CFM ![](/ubbthreads/images/graemlins/shruggy.gif) My low deck street stroker motor had a six pak set up on it until I swapped the heads to a set of Indy 440-1 with a Indy 400-3 intake. That six pak set up works great at the track and on the street ![](/ubbthreads/images/graemlins/thumbs.gif) As far as the CFM on the stock six pak carbs. the factory rates them at 350 CFM on the 440 center carbs. and 500 CFM on the outboard for a total of 1350 CFM ![](/ubbthreads/images/graemlins/shruggy.gif)

Yep, 350 and 500 are the way Holley rated them using the irrelevant 2 barrel formula. As I said earlier D.C. listed them as 295 and 425 which lines up perfect with the venturi and throttle bore diameters of similar 4 barrel carbs.
In theory, there is no difference between theory and practice. In practice, there is.

Six packs are cool and work great, but I wouldn't want one on something I was going to be racing every weekend. Much easier to work on a single 4.

i have it down to a science and i have actually caught myself bitchin bout trying to change jets on the secondarys on a 4bbl
an fuel lines on a sixpack makes life much simpler
Ray, you're the exception, lol. No doubt they work good when setup correctly. Your car flies and your advice was priceless when I was dialing in Dad's six pack. ![](/ubbthreads/images/graemlins/thumbs.gif)
