Reality of a 6 pack?

[aris_unlimited]

Hey guys I was just wondering in all reality if my wishes for a 6 pack are overrated? I have a 440 that will be built up to about 500 hp. I know that the 6 packs main carb is a 350cfm and the other two are 500cfm's. I was thinking I would make the main carb a 500cfm as well if that is necessary. Or in all reality would I be better off going with a 4 barrel? I would like to stick with a 6 pack if at all possible, but if it won't be able to manage the power I am expecting out of my motor obviously I will have to switch. Let me know you're thoughts, guys!

Making 500 hp with the stock 69-72 bb 6pk carbs is no problem. Also a 4bbl carb will do the job easier just by the tune.  I run a 6pk on my engine, I don't know why tho....maybe the wow factor or it was just what I had laying around at the time when I bought my car. I can say this. You will have more moving parts to keep working with on maintenance with the 6pk. They are not a problem if you know how to work on them and understand them. Don't expect to go much more than 6k rpms tho. But 500 hp is an easy number to achieve with any combo in air fuel you decide.

Just a thought...seeing that this is not a resto & the large outlay required for a six-pack I'd look at this 6-bbl injection system  http://www.fbthrottlebodies.com/

An EFI six will be very pricey right now. I want one though. Heard they were over 6,ooo$!  Can't swing that.   So I still consider the carb. six. But am not sure on my skills with it.  R/T

there are a # of factors here , first the 6 pack is rated as a 2 bbl not a 4bbl so the real flow rated as a 4 bbl is closer to 950 CFM total not that it will limit the power you want to get .
using a larger center carb is not really a benefit either , the small center carb has great throttle response & will get decent milage as well . The outboard carbs are difficult to rejet unless you get the Promax conversion plates .
Honestly I have found a single 4 bbl & the Holley Street Dom intkae or the Eddy RPM intake will make more power & cost less then the 6 pack , but having said that I also have a 6 pack on my 440 right now but  I also have a 950 HP carb & street Dom put aside if I decide to swap it out , the 6 pack looks killer for sure

I actually thought that 6-pack efi setup looked pretty good. But I'll be danged if I am going to spend $6k on it. I have found other efi setups for these for around $2k-$3k. As for the 6 pack system, I mostly want to do it for the "wow" factor lol. I am not a pro at tuning them or anything but that is something I can learn over time.......plus we have some really good mechanics out here that can help me with that kind of stuff.

Heck Edelbrock still makes a dual plane dual quad intake. Use two Carters or better yet Edelbrock AVS carbs.

Isn't too hard to tune. My D-66 dual quad SB runs--make that ran--very nice and smooth. I sold all my Holley and Demon stuff, lol

I used a single 4Bbl on my 440 and it had over 500HP - mated to a MoPar Performance aluminum intake it was an awesome set up.

Keep in mind that the 15 horsepower that was the difference between the 4 and 6 pak wasn't JUST carb, but the 4bbl 440 used 10:1 pistons, while the 6pak was 10.5:1. 

I bored my block .030 over, and ran 11:1 forged pistons and again - the 4Bbl carb was awesome.

Well a Holley Dominatior--race carb--which can be set up for street use by many custom carb shops--will make the most power. Scratch that--guess two Holleys on a tunnel ram will make the most power, LOL.

I would not worry about power--a 6 pack, dual Carters / Edelbrocks or one Holley will all be around the same HP give or take 20 hp.

Driveablity  will matter the most.

Which I feel the dual quad Carter / Eddys edge out, with the single holley a close second. Never had a 6 pack set up.

Other than the initial tuning and jetting, my 6 pack has not been touched in almost 4 years, with a couple thousand miles on it.  Power is plenty more than my tires can handle, so see no reason to need any more unless I wanted to put slicks on and race.  Zero issues with driveability, too.

Website says $2,678. One of these is going in my car. I'll let you all know how it is when I get it.

I set up a 340 6 pack on a AAR in 78 , it still has not been adjusted & runs great

I think the $6K comes in if a shop does the entire install and tuning, especially if done on a chassis dyno.  Once these things are set up (carb or EFI), they don;t change on there own, so a lot of people who say they suck are probably trying to tune them themselves with no experience, or were never set up right to begin with.  Altitude could also have an affect, but that would take a pretty significant change, like moving to Colorado from Texas.

  I don't think that is a turn key kit for that price.
