A better carburetor for my 47 G model six cylinder

[Vintage Copper 47]

I was talking to someone (I can't remember who) that said I can replace the single barrel Holly on my 1947 flathead G model straight six with a later model carb from an early 60's ford six cylinder.. Does anyone know what model car/engine he was talking about and the model/brand of the carburetor? My current carburetor is on it's last rebuild (it gobbles fuel, had some stripped threads, loose linkage).. I do have another Holly for the 47, but before I go into the expense of rebuilding my additional Holly, I wanted to check out the other carb option for possibly better gas mileage.. Thanks to all responses.. WALT

The stock carb is properly sized for the engine. Trying to second guess the original designer is usually not productive. Rebuild or replace.

If the later carb has same CFM etc... but an improved design.. why would I keep using a carburetor that is basically a soda can with some jets in it?

True that!
I don't have a specific carb in mind, but measure the bolt spacing of the base and visit the nearest self-serve yard. Throttle linkage and air cleaner can be modified to fit. Lots of choices: Mavericks had 200 and 250 sixes, AMC had 199, 232 and 258 sixes, Chrysler had the 225 slant six, Ford pickups had a 240 six, etc. A lot of these used a single barrel Carter that works well.
Hey, even Subaru used this Carter carb! Just check for a worn throttle shaft and signs of hammer adjustments.

When I was 15 my best friend bought a non-running '58? rover sedan with leather interior and aluminum body for 60 bucks. His dad was a shade tree mechanic and they took the carb off a dead rambler in the back yard and made an adapter from pipe and plate to mount it. We had a lot of adventures in that rig all the way through high school. Don't be afraid to experiment or adapt. It isn't rocket science!

Thanks GB... the carburetor I was thinking of is supposed to have the same bolt pattern & similar linkage... I will do some more research..

I have a six here that came with a load of V8s I bought last year. It has the side mount distributor so I think it's an H? Would it's carb be the same as the G carb?

Your "G" series carb is not hooked up to vacuum from the distributor. Wouldn't a newer carb need a vacuum source?

Found a seller on ebay last night that lists brand new "Carter type" Model YFA carbs for $80-90. Also some "Holley type" carbs. These are one barrel carbs like you want. They are made in China, not OEM so they could be great or not so great.

When I had my '42 G-series six, I considered modifying the manifold to take a Stromberg 97 as I always felt that the G engine would benefit from less constricted fuel intake path but never got around to trying it. Given that the ford six is 226ci I don't consider that it would be over carbed since the 97 was originally designed for the smaller 221ci engines.

most likely the one you were told about was whats called a glassbowl holley that was used on 223 OHV in the 60s. also falcons. they are good carbs but the biggest thing they suffer from is the bowl leaking from being over tightend. there was also the same carb but the bowl was diecast.


we run 2 of them on a hot-rodded 192 ford in a model A, but also run a single carb of a H motor in another model A with a hopped up 192. H is similar to your G motor. the H has vacuum single for the later distributer


im not sure what the 215 motor had on it, which was the first 6 OHV after the H and before the 223.

The 215, had a glass bowl Holley. My brother and I ran 2 of them on a fenton manifold back in 1969 In a '52 Ford with a 3 on the tree. That ohv 6 would give many flat v8's a run.

If gas mileage is the goal the later carbs from the 140-250 engines that was produced when mileage was an issue might be a better choice.
Or find a modern carb and adapt it.

I am running two of the glass bowl type Holleys except with die cast bowls on a 226 in my avatar. It has a reground cam and some other goodies. After I got the bowl leaks resolved (die cast bowls are easier to stop leaking than the glass bowls) I have had no other carb problems in over 10 years. I got them from an O'Reilley Auto Parts store, carb for a '54 Ford 6 cylinder half ton truck. They had one in stock and the second came in 2 days. They were remanufactures in a real Holley box. Ten years ago they were about $160.00 each.

amodel25,
Did you hook up a vacuum to one or both carbs from your distributor?

[Charlie Stephens]

If there is still a thing such as a real auto parts store (probably harder to find than the gasket) maybe you could look up the base gasket for your carburetor and then see what it also fits. Then go from that list to engine displacements. Good luck.

Thanks Charlie...

Toby... It's a crab distributor.. only vacuum was for the wipers..

The carbs used on the 144/170/200 sixes in the '60's were also a crude piece of work, your analogy of a soda can with some jets is close to the truth. Most were also Load-a-crapic carbs, not that it matters in this case.

The carbs used on 240 and 300 c.i. truck sixes might be a better bet.

I never swapped any on the flathead six but I did swap the glass bowl holley for the autolite off of a 1966 f100 240 six. WOW what a difference. Power wise, no more maybe a little less, smoothness over all other driveability day and night better. Of course reading this you can see how I feel about holleys, none better when you want all out performance but far from the best for overall driveability. Once running correctly those little autolites can't be beat.

They look great...but not my first choice for fuel economy..

The Holly 847 is the stock carb for my 226... the later Holly 1904 was used for the falcons, etc...

What is the Autolite carburetor model no.?

"What is the Autolite carburetor model no.? "


The Autolite model 1100 one barrel carb was used on 200 and 240 sixes in the mid 60's.

The front carb only. It seems to work good. Good acceleration, runs and idles smooth. Decent economy. I have been told by the experts that it should not work, but I didn't know any better so I guess it did.

In talking to Charlie NY... I am going to keep with the Holly 847.. Shipped the carburetor to him today for a quality rebuild!
