Need Y-Block help, Carb Advice?

I've got a 292 in a 55 thunderbird. i'm wanting to take off the "big mac" carb and put on a regular holly. is there a holly that will bolt to this intake? i'm thinking a 450cfm will do the job? i will retain the stock air cleaner. what do i do?

 

Upgrade to a 57 & up intake or you'll need an adaptor. Whats wrong with the stock carb?? You just have to practice with a fire extinguisher....LOL

If you upgrade from the stock carb, you will need a 57 or newer distributor to go with it. The loadomatic dizzy needs the carb it came with to work. The best bet is like Shoebox 72 said, go with a 57 manifold, a 57 dizzy, and I would sugest an Edelbrock 500 carb.

 

what happens if you dont change the distributor. I just changed to a larger 2 barrel on mt 272. just wondering!!!

 

If you are going to do all that work , why not a bad *** looking 3X2 set up . It will cost you the about the same as a 4 bbl intake , carb and dizzy . I have that setup and you only use the 2 bbl untill your foot gets heavy ! 3x2 set ups are just way kool too ! If you are at a show or cruise and you open you hood up , you will get more compliments than a 4 bbl . I think the HP is about 10-15 more that a single 4 bbl is also . They are not hard to set up and all that stuff people say . They are easy and you won't keep messing with it either ! GOOD LUCK on your choice !

 

There is a carter carb that was used on 56 mercs that will bolt to the teapot intake but they might be hard to find so you will be better off with a 57 intake and distributor like mentioned above and use a modern carb. Jeff

 

Does it cause va*** advance issues and hesitation in drive on take off!!!

 

Carter WCFB with the small bolt pattern, also used on mid-50's Mopars. I had one from a 55 Dodge on a hopped-up 292. Worked good with great throttle response. But if you go this route, you'll want to change the dist. to the later version to get a decent advance system.

 

Rebuild the original! it was made for that motor and will do just fine don't throw good money at it.

 

The LOAD-O-MATIC distributor does not have a mechanical advance. Advance and retard are controlled off of ported and manifold vacuum through a special power valve. If you go with a later carburetor, you need to also go with the later distributor. You also have a 6V distributor now, but the 57/ will be 12V. I am not sure about the points, condensor and coil update.

Call PONY CARBS and talk with them about redoing your HOLLEY 4000.

 

a carter wcfb will bolt right on, i picked up one for $25 and a kit for $35, and its still sitting on the shelf just the way i bought it..then i bought a 57 intake for $60 and a like new edelbrock carb for $100 and its still not on the car, couple of weeks ago i bought an edelbrock three carb setup with carbs, and it has not moved sence the day i bought it. but the wcfb will bolt right now.

 

it runs fine, just thought i would upgrade to something more common. to avoid future problems. i've got the engine stripped down for a cosmetic restoration. my distributor has a normal looking vacuum advance. the car has already been converted to 12V. i was thinking about putting a pertronix kit in the distributor also.

 

i take it that the wcfb is not the same as the afb?

 

yes the wcfb is different then the afb, i think that some of the wcfb's have a large bolt pattern as well so you have to look for one with the small pattern, heres a couple pic of mine. the bolt pattern is 3-7/8" x 3-3/4"

 

What most don't realize here is you'll need to upgrade your 55 Tach drive dist. , which is a dead end because you can't because it is all vacuum. So, if you change carbs, you need to ditch that (1955 Valuable, tach drive dist, at least $200 buck distributor!) for a plain jane cheapo or a proper tach drive tbird job that goes for 5 to 600-no ****, which IMHO is a little hard to take. But there are comprises available here, you should decide which one's for you.
It's just a small can of worms.
I prefer the Aluminum Blue thunder Intake-Looks stock but not and adds an easy 25hp AND a new four barrel of your brand pref, 500-600cfm is adequate. It outperforms the 3-2 setup on the dyno and is more reliable. Barry grant makes a killer 2 barrel that does look and probably performs great too on the Eldebrock 3-2. The best 3-2 Eldebrock 573, All other brands a #'s are weakstick.
Check at this place http://www.ford-y-block.com/ on the exact info on that dist. issue AND many more Yblock pertinent facts.
Or why stop at 3? How about high dollar webers on this this new offer?

If the car has a later distributor and has been converted to 12V, you would be better off (IMO) to find a later ECZ-B intake and mount a current 4160 HOLLEY to it.

The WCFB would require more effort.

- CARTER WCFB-

 

We did and he has stated the distributor has been upgraded beyond LOAD-O-MATIC. He only wants a cheap 4V upgrade.

-How A LOAD-O-MATIC Distributor Works-

 

ok, so I reread the posts and I still can't find where it is NOW, NOT a loadamatic dist.
But, anyhow I agree with "oddrod46" in the first place IF he just wants a cost effective improvement-Rebuild the teapot holley-it's a simple way to go.
Just mho too, don't want ruffle any feathers.

 

The cheap route would get the small carb, post '57 intake, and get an adaptor for a big AFB style carb. The big carb intakes cost quite a bit these days, if you can find them.

Also, that weber intake looks AWESOME.

 

can you still buy a distributor for a 1964 292 cid F-100 truck?

 

yes you can, i found it at napa # NRD
482808

 

Just an FYI. Distrubutors will work with 6 or 12 volts, the voltage is irrelevant. The ignition coil is what has to be the same as battery.

Billy

 

Unless you stumble upon a 3x2 setup for super cheap, this isn't realistic. A 3x2 mainfold will cost 3 times that of a stock 4bbl. Then even if you use plentiful 94's for carbs, by the time you buy 3 of them, get kits, and buy or make a progessive linkage, you'll easily have more than buying a new Carter AFB. If you wanna run three 97's, you'll have at least the cost of 2 new AFBs into them.

 

A 1957 or POST-'57 intake would have the large pattern like a modern Holley/Edelbrock/AFB would have. A PRE-'57 intake would have the small pattern.

As stated the cheap route would be to rebuild his 'towering inferno' thats on there now. BUT, as he stated, its running well he just was considering an upgrade. If its cheap he's looking for you don't get much cheaper than not fixing whats not broke.

-Bigchief

 

Looks like you got enough answers on this one . . . I would go with the first one from Shoebox72 . . . .right on the money.

 

We'll then someone took the good intakes off the engines I bought!

Bigchief does have another point in that, if it isn't broke, don't fix it. And you can get an adaptor for your ECZ 9425A intake, so it can accept modern AFBs, however im unsure how well those intakes flow compaired to the Ecz 9425 Bs.

 

No feathers ruffled. I am only going by his statement(s). I am ***-u-ming he has a later distributor. I cann't afford to lose any friends as I will stop learning...

If his appears as this, he hasn't had the upgrade.

LOAD-O-MATIC Dual Diaphram-

 

Well, the actual distributor ***embly yes, but the points would be different for different voltages would't they?

 

How many times are you going to keep bumping this thread up tonight ?
I have seen this same thread 3 times tonight at the top !!! You only have a couple choices . There are no other ones .

 

I believe this is called a discussion. And I guess as many times it takes to understand and correct the problem.
