Holley 847 Carbs

Recommended Posts

A few questions about twin carbs, I bought the Offey twin carb intake for my 218 engine, which carbs to use is my problem. Ive heard that the stock Plymouth B&B carbs don't work well in pairs. Langdon suggests that I use his two barrel Weber-Carter carbs and everything I have heard about them has been good but to me they do not look period correct and to use a Pinto carb on my 48 Plymouth makes me shudder at the thought. Vintage Speed suggests I use the Holley 847s which come from the Ford Flathead six, there supposed to be half the size of the Holley 94s. The 847s are a single barrel setup and will fit my intake without any adapters. I'm leaning on getting the 847s but just wanted to ask if any of you people have any knowlage of this carb in a twin setup? Vintage Speed costs are 155.00 and 85.00 core charge for a total of 480.00 bucks less shipping. That's a lot of Green to hand out and not know anything about the product. I thought the Holley 94s and the Stromberg 97s were a little bit too much for the 218 in a twin setup. Any Thoughts?

I am running Carter YH carburetors from a Chevrolet 216/235 I/6 on my 218 Plymouth I/6. I have not had any problem with them. I buy them at the swap meet rebuilt or NOS for about $70.00 each. They come in two different width bolt pattern. The narrow one for early chevys and fits early Mo Pars. The wider has the same bolt that the later Carter Ball and Balls have. I have Carter Ball and Ball carburetors with both the narrow and wide bolt spacing.

Nort sure where you heard that. I, and several others on this forum, are using a pair of B&B's. I have driven over 30,000 miles after making the dual conversion and have not had any major problems with my carburetors.

The "Pinto" carbs, (actually I think were from Escort V6's), are $85 a piece from Langdon. I have run them for about 25 k miles. I thought I was having a mixture problem awhile back and bought a pair of 847s to get the retro look you mentioned. They were so bad I sent them back. But while I had them I did some comparison and found the venturi were actually larger then the C/W from Langdon. I did more work on my carbs and ended up purchasing another from Tom. I have about 10 K on the new one with no issues.

$85 for a carb is a pretty good solution to me considering my time is money also.

One thing to consider is the total cost. Besides the carbs you may need to buy adaptors to fit them to the manifold, linkage components, and air filters and maybe adaptors for them as well. I've been considering switching away from the Ball & Ball carbs and those little extras add quite a bit to the cost of the carbs.

I run two Carter B&B carbs on my 218. It runs great. The problem I have, here in the south, is engine heat causing the gas to boil in the lines and in the carb float bowls when you shut it off in hot weather. The engine floods and the car reeks of hot gasoline. Towards the end of summer I switched from Shamrock and Chevron gas to Shell and the problem mostly went away. Last week I filled up at a Shamrock station and the problem came right back. Maybe too much alcohol in their gas. Other than that, the B&B carbs run great on mine.

I agree with Don, as my Dodge trucks use factory installed twin Ball and Ball's and they have always performed flawlessly too.

Thanks Guy's for sharing your knowlage on the Carbs. I do not remember where I heard that the B&B Carbs would not work well together. I too want the most for my buck and that is why I asked about the 847s before buying them. I already have a good B&B so I will purchase another one and go that route. I will also not have to worry about the spark advance not working right with different Carbs. I live on the Northwest Coast so maybe the Fuel boil problem will not be an issue, it's pretty cool here most of the time. This Forum has been a great help with my 48 Plymouth project, I have found many answers by reading here, Thanks again for your insite. Flatheadjim.

This is a little off topic and I probably should have begun a new thread but here goes.

I am rebuilding my Carter B&B. I've taken it apart and noticed when I took the plug (part 14-37-11) there was no ball inside. Ball (14-37-30). How important is this ball and where do I get one? They don't come in the rebuild kit.

Nothing is ever easy.

I also saw that the air mixture screw which is a needle valve had the head broken off. I took a hacksaw and cut a slot in it but I guess I would like to replace it. Are they available or am I going to have to buy another carburetor to cannibalize?

I would appreciate any help - I need to get it running.

thanks,

d-
