FORD 6V CARBURETION TECHNICAL INFORMATION

Ford Holley Tri-Power Technical Information

FORD 6V TECHNICAL

This technical bulletin(5th Edition November 2010) is aimed at those who own a Ford Small or Big Block Powered automobile with a Holley 3x2 (6V), Model 2300 Carburetor setup (Holley Lists 1673/1674; 2436/2437; 2497/2498/2499; 2867/2868; 2881/2882 & 3208/3208) on any of the following motors, including 260, 289, 302, BOSS302, 351C, 352, 390, 406, 427, 428, 429(385 Series), BOSS429 or Lincoln 430.

Here are five pics of my personal Joe Bunetic restored (Apr '03) 289 6V intake manifold with Holley List 2881/2882 carburetion....pic#1,  pic#2,  pic#3,   pic#4    and  pic#5 If it looks familiar, you may already know it for what it is, a Ford 289 Tri-Power with List 2881/2882 carbs!

Now if your tri-power looks similar, but it resides in a slightly different setting, have a peek at this graphic! If it looks familiar, then you probably know it for what it is, a diagram of the Ford Holley Big Block Tri-Power (Lists 2436/2437; 2497/2498/2499; or 3208s)! If you need some technical help with these carbs, you have come to the right place on the web! 

If you would like a further sample of some of the information that has found a home in the TRI-POWER BULLETIN, have a look at the following remembering that it will take a bit of time to down load each graphic! ******Author's429SCJ Tri-Power with MoparSixPac Carbs

FORD 6V CARBURETION IDENIFICATION GUIDE

 351C 6VFORD 366 NASCAR ENGINE PROGRAM

Bob Champion's 351C ,  The Cleveland 6V intake manifold.  According to  Tom Vaught, currently Ford Motor Company's Boosted Engine Design Engineer and former Holley Engineer on the design team responsible for the development of the Holley Carburetion for the Cleveland 366 6V intake manifold, this 6V carburetion program came about through Ford's 366 NASCAR Engine program where they built 500 366ci Cleveland motors with 6V intakes for NASCAR competition, only to have NASCAR disallow their use, causing Ford to physically destroy all the intakes. As apart of the Ford NASCAR 366 Engine program, Tom Vaught of Ford Motor Company (Holley Carburetors then) was a member of the design team that  built the Holley 2300 6V carburetors for this special Ford project, using Holley 2300 vacuum secondary 6V carburetors.

 During the testing, it was determined that the 1350cfm flow of all three carburetors was too much air and fuel for the Ford 366 program so these carburetors were sleeved for the Ford NASCAR 366 Program. After the comprehensive destruction of the 500 original motors, intakes and 1500 Holley carburetors, very few survived.  The few in existence today were hiding on shelves and missed the actual Ford directed physical destruction.

Recently, a single Holley Sleeved 6V carburetor was sold with one of the very few 4296V intake manifolds still hanging around.  This intake manifold was an original which had remained in the care of Buddy Barr Castings in Los Angeles , being  sold in late 2004 to a Ford collector in New Mexico. Below are several pictures of the original Holley Sleeved 6V carb which  belongs to Eric Hirengen of  Farmington, New Mexico.  This carburetor is an ultra rare piece.  When Ford cancelled the Ford 366 NASCAR program, they decided to abandon the Holley 6V carburetors which they had Holley develop for them.  Holley then offered them to GM and MOPAR. GM was not interested, but MOPAR was. These specific carburetors were then modified and converted from vacuum secondary to full mechanical in the form of Holley List 4782/4783s which MOPAR offered for competition uses thereafter.

I run a set on my Ford 429 6V intake. They work exceptionally well.  These carburetors were returned to their un-sleeved size of 1355cfm total for all three.  Tom Vaught also indicated "that an engineer at Ford at one time had two complete sets of sleeved carbs for a 429SCJ  71 Mustang, one set on the car and a spare set, so there are more out out there" besides Eric's single carb.  The sleeved carbs ran very well on the 429 Mustang. Here are several recent pictures by the author of a NOS 366 6V(Cleveland 6V) intake recently sent to Rick Walker of El Cajon, California (May '03) to set up the Mopar series SIXPAC Holley carbs for the customer.....pic#1,  pic#2,  pic#3,   pic#4,   pic#5,    pic#6   and   pic#7.

Or for a nice photo of a FE Tri-Power! Here are two of Harris May's photos of two very nice FE tri-powers, including this Galaxie setup and his personal T-Bird setup. Very nice detail on Harris May's air cleaner photos for people looking to see an all original correct setup.

351C  INTERCHANGEABLE INTAKE

For the ultimate rare intake, have a look at this series of four pictures of Tom Frayer's recently acquired Interchangeable351C intake built by Shelby in the 1971 timeframe. This intake was designed with a series of replaceable top plates so that the discriminating owner could run either a single Holley 2 barrel, a 3x2 Holley setup, a 2x4 Holley setup and an inline Autolite four barrel. Interchangeable351C/1, Interchangeable351C/2,   Interchangeable351C/3, and Interchangeable351C/4 .  Recently Ron Duly took these three pictures of a complete Interchangeable 351C intake manifold complete with the 3x2 top plate along with a set of Corvette Holley 3x2 carburetors and linkage....Interchangeable351C/1a,  Interchangeable351C/1b,  Interchangeable351C/1c.  Very nice pictures and many thanks to Ron Duly for sharing them.   Ford 351C Interchangeable Intake Manifold Article-"3 Into 1 Will Go" Don Green, CAR CRAFT Magazine June 1971 Page 52

A picture of another similar intake recently showed up in MUSTANGS & FORDS Magazine, October 1999 page 96. That intake belongs to Rick Kirk in Ripley, Oklahoma. Rick indicates that he acquired this intake with the carburetors in the mid 70s directly from Ford.  Looking closely at the carburetors, they are most likely a original set of Holley List 4782/4783 Vacuum secondary carburetors with side hung fuel bowls.  As Tom Vaught from Ford Motor Company indicates, these were developed specifically for Ford for the 429 6V intake as well as the BOSS429. They were also used on the Ford 366 Engine Program (CLeveland 351C 6V), but Holley had to sleeve them to reduce the airflow to make them work on the Cleveland motor.  When the program was cancelled for the Ford 366 Nascar Motor and the 429 and BOSS429 6V programs, Ford was no longer interested in these carburetors.   Holley asked the other manufacturers whether they were interested in these carbs and Mopar immediately  answered up, so Holley ended up producing this list series for Mopar.   After further changes, the carbs were converted to mechanical with full metering blocks, accelerator pumps and progressive linkage.  The carbs were offered as a performance option replacement for stock Holley Mopar SixPac vacuum secondary 3x2 carbs with a special Edelbrock produced set of progressive linkage and fuel log. 

How about Santee California's Fuzzy Knights very nice 63 1/2 Falcon Ranchero with original 260 V-8, 4 spd and  Ford Factory 260 6V with the very rare 260 Holley List 2667/2668 carbs restored by Rick Walker of El Cajon, Ca.

Ford accelerator linkage technical help.....here are 20 links with jpegs of various Ford Shop Manual diagrams of linkage setups which may be of help when trying to re-install Ford 6V intakes when the original Ford 6V linkage connections are few and far between, plus a few diagrams on the intake manifold, emission control connections, road draft tube  and air cleaner information for the Ford 6V setup.....Remember Ford Factory 6V Air Cleaners are the same for Windsor and FE 6V carburetion setups...........
