wow picked up free 6pak

Hey everyone. I'm 17 and own a challenger. Get this. I picked up a set of 6-pak carbs out of a challenger T/A for free. The carbs are complete but need to be rebuilt. I would like to rebuild them myself and then put them on my car eventually.

Does anyone know where I can buy a kit that has everything I need including linkages, pins etc?

I still need to get the intake. Anybody have a nice used one?

Also, I here that tuning a 6-pak is a bitch. Does anyone have any tips?

Thanks y all

Koller Dodge and Olson Dodge will give you some pretty good prices on those items, as well.

Thanks a lot guys. Do you have any other tips on tuning them?

Also, I picked up 4 perfect 15x7 rallyes, original T/A spoiler, flip top gas cap, 3 row radiator and the 6-pak air cleaner all for free!

lucky guy!! but, and i say a big BUT!! check them out thru and thru before you sink any money in them. if the throttle plates are cracked,thats 150.00 for each one. if there gummed up, once again, that can cost some dough. as far as tuning, well thats another story. i'v seen them at swap meets and most of them need a complete rebuild. total cost, anywhere from 200-400$ depends on the damage. good luck.

6pakman is right, if there is any problem with the carbs, new Holley's from Mopar Performance are $324 for an A engine outboard, and $414 for an A engine center (auto tranny), and $454 for an A engine center with standard tranny... if you have a B engine, they are $518 for the center, and $324 for the outboards...(prices are for EACH carb...)

oof, pricey... i don't know if this is the route i would go...abusive on the wallet...i'll bet ya get some pretty sweet power when everything is tuned right though...

Yeah

I was driving down the street one day and I saw a yellow T/A and a blue 68 dart in a garage so naturally I turned around. I met the owner who is probably in his late sixties. I asked if had any spare parts he wanted to sell. Key word is sell. He said I don't have much but I will give you my old 6-pak, original T/A spoiler in nice shape, brand new 3 row radiator, flip top gas cap, and original 6-pak air cleaner assembly! When I got home I needed to check my underwear. I had only heard of phantom deals like this but I never thought I would run into one! Pretty cool.

i like old people with MoPaR's that are too old to race anymore......they give away great stuffs so younger peoples can have fun!! that happened to my friend in Illinoise, but it was chevy parts...i think he has a '56 Chevy...very nice shape! it's all stock! not a racer, just a cruiser.

i hope i run into some kind of deal like that sometime....

Idea

Save yourself a world of headache.

Have you ever noticed how many guys use 6 pack setups at the track? (not many)

I'm not knocking them, they are very cool. BUT a 4bbl will give you as good, OR BETTER, performance with a lot less hassel.

Go to a swap meet and Trade the six pack carbs for a decent aluminum 4bbl intake for what you've got.

Then with the money you were going to spend on the six pac manifold and set up stuff, you can buy a brand new demon carb. Maybe an edelbrock, and have some cash left over for a tank of gas or two.

Heh, heh, heh...

Tuning is the fun part

Depending on your combination will determine the extent of tuning. I have been able to bolt on, set idle, read plugs and adust only the main jetting on some mild engines. Other times I have had to make mods to get the combination to work correctly on more radical set-ups.

Best thing for you to do is start reading about Holley 2300's series. Majority of your adjustments will be with the center carb, it does most of the work.

Best of luck. Heh, heh, heh...

Oh by the way.

You get it working correctly and it's a great setup for the street. Power and economy.

Just realize you cannot control when the outboard carbs come in. You can only influence them with springs/mods. Don't change to mechanical linkage. Learn to drive to complement when the outboards open, it's not like a double pump.

Good tips. Heh Heh Heh. During normal cruising it runs on the center carb and then the two outboads kick in when you romp on it right?

They will eventually be going on a 360 with port + polish heads, crane cam (I think its like 218 degrees duration and .454 lift on the intake and exaust) stock pistons, stock valves, headers, viscous fan. Not stock but not at all outrageous. How much balls will that setup have. Think I can hit low 14 high 13 with 3400 pound car, 2000 rpm stall, 10.5 inch wide slicks and 3.55 posi? I'm only 17 and this is my first mopar.

Bone stock 1979 360 = 245 hp
port and polish adds = ??? hp
crane cam adds = ??? hp
headers add = ??? hp
viscous fan supposedly = 15 hp

I'm hoping at least 300 hp. Any guestimates?
Also, does anyone have any general tips for tuning a six pack setup like this?

ok, first off, MoPaR's don't have "posi"....they have sure grip.

what kind of intake is a 6 pack? dual or single? cfm's?
do you know what the specs of the cam are?
what is your compression?

i have Desktop Dyno 2000 and can give you an ESTIMATE on your HP at the flywheel...just gimme more info and it'll be a little more accurate.

sorry, no tips on the tuning...

Since we're getting picky...

There is no "c" in 6-Pak.

There are however 3 carbs. The center is 350 CFM, the two outboards are 500 CFM each, total CFM 1350. Remember however that 2Bbl carbs are rated at 1.5 vacuum, 4Bbl carbs are rated at .5, so the CFM equivalent of the 6-Pak is 964 CFM.

Alright Toad uhm I mean Road Runner. Only kidding!!!

1979 360 with 9:1 compression
1350 cfm
218' duration .454 lift on both the intake + exhaust

I don't know if the six pack manifold is a single plane or a dual plane. I would imagine its a dual plane.

Anyone out there know?

Thanks a lot Road Runner.

no problem...but first, i need some more info...

do your heads have 2.02 int. and 1.60 exh?
what kind of exhaust? if headers, big or small tube, and will you be using mufflers?
do you have any more info on the cam? is it hyd. or mechanical?

i guessed on some things, and heres some numbers i got:

243HP @ 4000 RPM
420 ft/# torque @ 2000 RPM

everything drops, there is not much of a raise... at 8000 RPM, your makin 8HP, and 5 ft/# of torque...

these numbers are at the fly too...

the duration is what's killin your performance...are you sure it's 218? what is your advertised duration? not the duration @ .050...

where did you get the camshaft from? maybe i, or you, could look it up and get the specs...the only thing i see for Crane in my P.A.W book is dual grinds...not single...

heres what the levels are with a Crane Powermax Cam in my P.A.W book...
Code:
Crane Powermax Camshaft
Part No:     CRA-694301
RPM Range:   2500-5500
             Int   Exh
Lift:       .458  .465
Adv. Dur:    288   292
Dur@.050:    226   230
Lobe Sep:    110*
Cam Price:   109.95

379HP @ 6,000 RPM
374 ft/# torque @ 4,500 RPM
much better numbers in my opinion...

course, then there's this cam...
Code:
Crane Powermax Camshaft
Part No:     CRA-693801
RPM Range:   2200-5200
             Int   Exh
Lift:       .467  .494
Adv. Dur:    278   290
Dur@.050:    222   234
Lobe Sep:    114*
Cam Price:   118.95

382HP @ 6,000 RPM
388 ft/# torque @ 4,500 RPM
these are hyd. cams too... if you want, i can give you numbers on mechanical shafts + your setup...but remember, its just an estimate... these numbers are at the flywheel and with a dual plane... go to a really good single plane and the same cfm's...better hang on to your britches!!

Lightbulb Six Pack Tune up

There is a lot of good advice there, but I didn't notice any one mention having the carbs syncronized. A friend of mine bought a 68 Charger with 440 six pack. The first night out I noticed it wasn't pulling as it should. It should have put out about 450 HP. But we lost a race to a 440 six pack Challenger ( stock ) I asked Mark if I could check the plugs and have the carbs syncronized. There were 6 different types of plugs, lengths, heat ranges. Once we got a new set of plugs and got the carbs Syncronized. It was like a different car, with a very noticable hike in power. Moter cycle shops have the tools to sync the carbs. Good luck.

Quick Claims Adjuster!

Agree, there is quite a bit of good advice and tips. However, I would have to disagree with the statement that they are a “bitch” to tune. My 440-6pk engine is fairly radical: running Stage VI heads, high lift cam, 11 ½:1 compression, etc., but is quite street able and I did not have to go very far from the stock carburetor settings to tune it in. You see, all a six-pack set up is, is a four-barrel carburetor with an extra pair of vacuum operatated secondaries. Do you have to “synchronize” the vacuum operated secondaries on a 4-barrel Holley? No, of course not! So tune up the carburetors the same way you would a 4-barrel with vacuum secondaries. Not like a motorcycle or Weber carburetor set up.

My guess (based on your description of your engine) is that the only thing you will have to do (providing the previous owner did not really screw up the carburetors) is go several jet sizes over stock (stock is about a #61 or #62 jet) to richen up the center carburetor, change the power valve (stock is a 6.5), and make sure you have the correct fuel metering plates in the end carburetors. (“Year One” sells them. For your 360 engine, I would use the ones for a 340 six-pack set up). As for as setting your idle mixture, start with two turns out on both screws on the center carburetor. Then tune and adjust them as you would any other two-barrel. Yes, the front and back carburetors do have idle mixture screws. Set them for 1 ½ turns out and leave them alone. They really don’t do much since you really only idle off the center carburetor anyway. You only run off your main jets (fuel metering plate in this case) on the front and rear carburetor. As for the vacuum diaphragm springs, I left mine stock, which uses the real light yellow spring. Leave it alone unless it becomes real clear that you have a bog when the front and rear carbs open up.

Yes, a four barrel is a little easier to work on and tune for the track. However, I guarantee that the six pack set up will turn many more heads on the street and at the local cruise, when people see that emblem on

Question hey 72rr

Hey 72 rr...

What does my 400 make on you program?

I've worked it out to about 330(crank) with a g tech, but I'm curious whatthe desktop program gives you

400cid
4.372 bore 3.380 stroke
9.9 to one compression
installed quench of .054"
closed chamber heads
2.08 intake 1.60 exhaust
mildly ported and port matched manifolds.
dual plane intake
manifold exhaust
dual 2 1/4" dynomax, no crossover pipe
750 cfm edlebrock(vac secondary)
490 lift 272 duration 110 centerline cam
electronic ignition 8mm wires
electric fan
12deg initial timing 38deg by 3500rpm
2300 stall converter

I realize a bunch of this info is probably useless, but I figure more is better.

Thanks in advance for the reply.

you didn't tell whether the cam is Hyd. or Solid so i ran both numbers...

with Hyd. Lifters:
362HP @ 5,500 RPM
415 ft/# torque @ 3,500 RPM

with Solid Lifters:
387HP @ 5,500 RPM
433 ft/# torque @ 3,500 RPM

with large tube headers and open exhaust, here's what you get...

with Hyd. Lifters:
424HP @ 5,500 RPM
458 ft/# torque @ 3,500-4,000 RPM

with Solid Lifters:
447HP @ 5,500 RPM
478 ft/# torque @ 4,000 RPM

i also have yet ANOTHER program that will estimate your ET from your setup...

the info you gave me is close, but i'll need the weight, converter slip, rear end ratio, do you have a 727? i also need your tire height, fuel (octane), fuel pump gpm's, tire type (slicks-radials etc), do you have a hood scoop or cowl or ram air setup?

if i missed anything i'll let you know, but that should do it...

enjoy!
