The Evolution Of Factory Tri-Power/Six Pack and Dual Quad Intakes For The Street

[@CODA-Improvements]

My uncle worked for Holley Carburetor in Warren, Michigan from 1951-1970 as a shop foreman before deciding to open a tavern in Pa. When he passed away there were shelves and shelves of new in the box carbs for every setup imaginable, including a bunch of dual quads . My cousin took all of them and used them for a custom hotrod shop he owned in Philly. Thanks for jarring my memory, Uncle Tony!

[@vintagesavoiur]

Love my 6 barrel. That little 350 dead center on the intake gives phenomenal response and great gas mileage.

[@exploranator]

I always wanted a manifold that had the center carb feeding a low dual plane with a high-rise single plane stacked on and integrated with it so when you hit higher RPM, your four end carb throats are shooting almost straight to the pistons.

I did some manifold and carbs comparisons on my dyno last summer. I tested a mild 440 featuring E-STREET heads, 9.2-1 compression, MP .528 solid cam, 1-3/4" Doug's headers. The manifolds tested were; M-1 single plane with Edelbrock 750 carb Weiand TunnelRam with same 750 Edelbrock carbs Chrysler ShortRams with the same set of Edelbrock 750 carbs Results were M-1 455hp&504ftlbs Weiand TunnelRam 469hp&542 ftlbs Chrysler ShortRams 429hp&543 ftlbs The uptake though was that the Shortrams buried both other manifolds with their torque curve. 512 ftlbs@2500rpm and carried 500ftlbs to 4400rpm. They are a killer street induction system.

[@jamesblair9614]

Lots of information and lots to look forward to. For me, there’s just magic in a factory multi carburation system, and the early ones usually had elaborate air cleaners too, I love them!

In 69 my step dad bought my mother a brand new GTX Hemi 4 speed and she drove it back and forth to work about 14 miles one way. She never complained about starting it or how it ran or anything like that. If she could do, just about anyone could do it.

[@elmerfudpucker3204]

Spot on, and a great overview of the history of multi carb induction. It's amazing how far technology has advanced in such a short time, on automobiles overall. The "early days" of trial and error have definitely paid off.

[@easygoing2479]

I love it when Uncle Tony gets into these history/performance theory videos. Even though a well-chosen 4 bbl carb can match or even outperform a multi-carb setup, anyone who has ever owned-driven-worked on a 6 bbl or 2x4 engine (Hemi, anyone?) is familiar with the mystique and aura they exude, how you can so easily feel the power surge under your foot, the brute force in your ears, when they open up. And if you're an old-time Dodge/Plymouth guy from the 60's/70's, you're no doubt familiar with multi-carb setups; hence, Uncle Tony is the man!

[@georgewetzel4380]

Jensen did not offer a dual four barrel set up, it offered the "Interceptor SP," a separate model, through it's 73 model year, which is featured the Chrysler 440 six barrel motor, and yes, SP stood for six pack. Here's another interesting Interceptor tid bit for small block fans: later Interceptors used the 360, and Jensen offered a factory installed hemi-head conversion kit for it; I have no idea how many were sold or even produced.

GM also used 2 x 4 setups starting with the 56 Corvette on the 265 and carried over on the 283 . Pontiac also had the 421 SD with the baddest ones also using two fours . They were dominating NASCAR in 61 and 62 . Buick also used two fours in the mid 60's on the nail head V8's . Chevrolet used the 850 double pumper on the L88 starting in 67 . It was the largest CFM carb used by GM on any engine at that time .

So back in the day I worked for a race shop. And we had a 1962 Galaxie 406 tri-power manual as one of the shop cars. We beat on that thing mercilessly and we lightened it as much as we could get away with. It would run 12.95 on a good day a Bay Lands or Half Moon Bay. But tuning it for conditions was not trivial because by the time we got the car it had three center carbs. So running a jetting book was mandatory. We eventually knew all the atmospheric condition/jet combos that would work for the strips we ran. We never went outside the SF Bay Area or the coast. I'll bet we would have gone crazy inland at any altitude ... 🙃

[@tsmith578]

Hey there Uncle Tony .. Great subject. you just don't hear many people talking about duel carburetor or triple carburetor engines much anymore . when I was growing we would install duel carbs on different engines to see what kind of cool factor it made . The greatest challenge seemed to be finding the best intake manifold to go along with the engine build style . and also matching it with the Exuast header design . Too large of headers and we would lose too much low end torque . otherwise the tuning mostly came down to proper jetting and ignition timing . but what also was a great tuning acheavment was just often the simple addition was of a pair of spacer plates under the carburators spacers would often make one heck of a difference to be the icing on the cake for the entire setup to get the torque curve just right . Thank you for the video Tony . Tim from Wisconsin .

The Tunnel ram was first used on the 427 Hi Riser Marine engines .You could buy a 3 2 bbl .carb. setup for the 390 Ford engine a year before the 406 became available .The $427 Tunnel port used 2 4bbl.carbs in the 60's to win on the super speedways as the Hemi was limited to 1 4bbl. carb. The 950 3bbl. Holley was used on Modified Sportsman big block stock cars both Chevy and Ford until the Dominator became available .The 3 bbl was used in drag racing as Grumpy Jenkins took the back halves of 4 3bbl. carbs and joined a pair of each on his Tunnel Ram 1968 Camaro and found it to be a winning combination.

I've always been a QuadraJet fan. Tuned properly, it's a good carb. Stay out of the secondary and your small block V8 can get decent fuel mileage. Properly adjusted linkages on the secondary will produce great performance on the track as well. Unless your trying to get up there with the 8 second cars, a QuadraJet is a great all around "fire make it happener".

I've always liked Q-jets too. Some people just don't understand them and try to tune them like a typical Holley. You're absolutely correct about their ability to deliver decent fuel economy because of their small primaries but, they also sound great when those huge secondaries start sucking air!

Very informative but some of the information is incorrect, or I misunderstood. I have a 66 Pontiac tripower that is adjusted from the center carb. The outer carbs are dumps i.e. when you floor it they open up and dump air and fuel and you don't adjust idling with the outer carbs.They are also mechanical, there is no vacuum control secondaries. It is possible that they were modified to be mechanical but I've had this tripower since 79 and I don't think it was? I've seen vacuum secondary tripowers and they have a tube coming from the manifold to supply the vacuum. Mine does not have the vacuum tube access like those I have seen. I have heard from many people that a properly selected intake and carb will net better performance than multiple carbs. I suspect this is true but I did read where, I believe it was Cliff Ruggles, setup a quadrajet and dialed it in on a Pontiac. After several runs they swapped the single 4 barrel setup for a tripower. Without even dialing in the tripower the car performed better with the tripower. Were they using the wrong intake, too small of carb??? I don't know but I do know you'll have a hard time finding someone better than Cliff to tune your quadrajet.

Using a Holley on a dual quad, first thing I do is block the power valve. Easier to tune carbs doing that. I have a boss 302 that's near perfect even compression. I first tune a carb on that. Then switch them to a dual intake. Then final tune to the dual.

Can you do a video on multiple carb history? I once saw a 413 with 4 4bbls

[@bs23rob48]

Yes I seen it, there was a max wedge experiment, I knew the guy that had the setup after it was scrapped by Mopar. There's pics on web.

Can you make a video on off line stumble on carb?

[@stevehohnberger1963]

What do you know about preditor carbonation? I am running two of them on my 440.vary hard to tune them in to run.i would sure like it if you could school my son and I, so we can finally enjoy our 73 plymouth satellite sebring plus.

You say no Tripower before 66...but what´s with Ford FE and 3 holleys like on a 406 in 63?

[@moparnut6933]

Can you teach us how to install then tune the 6 pack?

[@AryDontSurf]

I'm gonna get one of those Ferrari Webers to run on my stovebolt.. .. I joke. But I do seriously want a Tri-Power Manifold when I build a small block for my pickup. I have 1/3 or the carbs already

[@Suzjoh825]

The multiple carbs are definitely eye candy
