I am getting to point in my build when I have to decide on my carburetor and intake combination. I have had the Weiand WC4D for a long time and always wanted to put it on my A coupe. The engine is a mild 327 hooked to a turbo 350. For guys that have run these- how did it turn out. Lots of old threads on them, but not lots on driving them. Four 97s set up progressively would be the plan or maybe just two of them? Should I spring for the new English 97s? Seems to be lots on good reviews on them. Thank you
The carb layout in that intake does not work well in a progressive linkage set up. You will definitely have a few lean cylinders and when you open it up it will probably fall on its face. I’ve only ever driven one on a 283 but a 327 shouldn’t be much different. I certainly wouldn’t want it on anything bigger than that. A straight up linkage with carbs jetted down a bit will give you the best result. Quality linkage is key with this setup. Stromberg sells a very nice setup that is the only way to go in my opinion. The WC4D is the best 4 carb intake for the street hands down over an Offy or man a fre. Set up properly they drive great but expect a lot time in getting it dialed in properly.
Hang on, I’ll let you know in a couple of months. My 283 is at the machine shop now along with my manifold and carbs . It is going in a fad T with a 5 speed and 3:55 jag rear. I have had 2 very bad 4 deuce experiences…..on the Edelbrock 360. When my engine went into the machine shop, they agreed to everything being dialed in correctly before I pick it up……I can hardly wait For my Maryland friends, Jim Bunting of JB Machine will be doing the carb work. He is our local 97 Guru….almost as old as the carb 97 number
Thank you, I thought this was the only 4 carb intake that can run progressively. Hrm2k- is that an English Stromberg linkage? Thanks
That is straight linkage that I made. I would rather run straight linkage these days to keep the fuel in each carb fresh...
I set up a Man-a-fre. 4x2 for a friend.(Like Milner’s coupe). Used a uni sync. Linkage has to be perfect. No flexing. All carbs have to be matched even. Took a little time but ran great!
@TexasSpeed just drove his from forth worth Texas to Bartlesville Oklahoma. May have some thoughts @Moriarity does your vet have this or a man a fre on it? had a buddy years ago that got his man a fre dialed in and it was a very sharp responsive set up. Dang near direct runner intake so it’s gonna take a minute to get it right
Maybe it's just me, but I've never had much luck running multiple carbs on a car with an automatic. But not any problems when used with a manual. Being able to drop them into neutral at a light helps with the idle. I had 3 Strombergs on a Y-block with an auto in my 57 Ford. Idled like crap. Took it off and put it on my 29 PU with a Y-block 4 speed and without touching anything it ran great. I've used both straight and progressive linkages with good results.
Looks like the automatic could be an issue. Would a straight linkage running on a front and back carb (block 2) starve the cylinders? Thanks
I would definitely run the carbs with straight linkage. Not progressive. Not sure if the Weiand has balance ports. But I would set it up like it didn’t.
I had 3 Stromberg 48’s on the 350 in my coupe with an automatic with progressive linkage. It wasn’t a road burner but not that bad either
@Moriarity did you make the extended shafts and support? Would it be lean if two carbs were blocked off? Thanks
I made the support but did not make the extensions. Stromberg 97's are only 155 cfm each so 4 of them are 620 cfm. why not run all of em? I have 4 97's on my internally stock 49 Cad 331 in my 40 with straight linkage. I jetted it at 41 and it runs great, idles as smooth as a gravy sandwich at 600 rpms, has great throttle response and gets about 15 mpg around town. whats not to like?
Wow, that is a nice engine! I am just worried about feeding too much fuel. Who made the extensions? Do you have a bearing or bushing in the support arms? Do you have a part number for the bearing or bushing? Thank you!
The extensions are old, I believe they were Eelco items long since extinct. They should be easy to make on a lathe though. I made the support and I made the bushings from round nylon stock that I had.
don't worry about to much fuel, that wont be a problem, you almost always have to jet down running multiple carbs. but running progressive you will not have the air volume needed to properly supply that engine. Remember when this intake was designed the largest small block was a 283. If you set it up progressive, the cylinders closest to the carbs will get more fuel and and the others will be lean. Yes you can do progressive on 3 2 barrels, But I have only ever had good success with that on Rochester 2GC's. With 97's or 94's they always ran better with straight linkage.
If you use original carbs the most important thing is to make sure the shaft and bushings are not worn out and the blades fit the bore correctly. If they don’t, sending them to someone like 97express to get the bases refurbished is money well spent. I can tell you from setting up multiple carb intakes with 97’s to just start with them completely stock with straight linkage and go from there. You’ll be surprised how well it will behave with them properly set up.
Hey guys, who make the linkage for this setup with the Holley 94s? I want to put this on my motor and have the intake and rebuilt matching 94s. Just need the linkage
Not true weiand even made progressive linkage for it. MANY people have run progressive linkage with great success. Most setup the 2 middle carbs as primary carbs and the outer carbs kick In at whatever throttle position that you set the linkage up for
