I'm just curious, and I searched the internet for a while and couldn't find my answer. I've seen a few cars with this engine and just drove by one today out on the road with the "440-6" badge.

Anyway, I got to thinking.

How do 3 two-barrel carbs feed 8 cylinders?

I won't bore you anymore, just explain it to me please lol. Thanks in advance.

 

The same way a 2 barrel feeds 8 cylinders.

 

You may want to change your search from SICK PACK to SIX PACK. 3 carbs x 2 barrells each= the Six Pack.

 

Alright... enough with the sarcasm. I think I can get real low tech on you. I'm by no means a mechanic. Those 3 carbs feed the engine the same as one carb would feed it. 3 carbs can be hard to keep "tuned" in properly as they run in sequence with each other not seperately per say, so you could change that to a higher flow single carb. The fuel is distributed to the manifold the same way with 3 carbeurators as it is with one.

 

I'm obviously "by now means" an Eglish teacher either.

 

I'm going to leave that one in honor of you Craz3d... I'm gonna go 6th grade english teacher on all your posts now though. My screen's gonna have red marks and white out all over it!

 

Unless the carbs werent tuned right...

 

Or some were called 3 dueces!

Generally speaking the engine runs on just the center carb under light throttle and general cruising. The outer carbs come into play in succession as you start to bury your foot into it. When all 3 carbs are open they just feed more air/fuel into the engine to make more power. It works the same as a 4 barrel carb just with two extra barrels.

 

Ahh that makes sense. Thanks guys. lol @ "sick" pack. I was tired.

For some reason, I just forgot that carbs sat above the intake...I was just assuming that there was one "port" for each cylinder like direct feed.

That's a pretty interesting set up...I know that they're really hard to tune.

Thanks for the clarification.

 

In the early seventies I worked at a small Chrysler garage as the parts gopher and car washer. There were a couple of customers that had 440-6v in the Challengers. When they brought them in for overnight service, after everyone was gone and I was left to close up the building I would start one up and listen to her idle for a little bit. What a SWEET sound that was.

 

When I was a teen, I bought a 1954 Olds, And I think it had a 324 bord and stroked with 3 deuces and progressive linkage. I forget what the actual CID was. Hell of a car in it's day for a kid to have. Only weak link was the u-joints, only lasted about a week Never had much problems with the carbs though. I did tweak the linkage though to get all three carbs come on earlier. Old school attempt at fuel economy gone bad. The way it was set up was the center card would fuel all the time and the more throttle you would apply, the more the front and rear carbs would come on if I recall.

 

 

A friend of my dads (many years ago) talked about his 440 and said if you really wanted to see the engine come to life then hook up two 4 barrels. I guess the engine can really suck the air in if its able to. I personally don't know much about those motors though.

 

I was lucky enough to have a 1966 GTO with a 389 with 3 dueces (Tri-Power), it ran great off the center 2 barrel and when you punched it down halfway on the pedal the end two kicked in and it had a great sound, especially with the header's opened. All you needed was the intake manifold and the right camshaft to handle the extra carb's. You could put that setup on a 389,400 or 421 cubic inch Pontiac block. Probably would have worked also on a 326 Pontiac engine. Pontiac had a 421 Super Duty engine in the early 60's with 2 four barrell carb's that I would have liked to have dropped in my GTO! Those were the day's.
