I am using a stock cast iron 4 barrel intake on my 265 sbc v8. Is it possible to adapt a 450 cfm Holley carb to it? Not sure which adaptors I need. Any help is appreciated.
The one with 8 bolt holes they may or may not be threaded. Some are solid some are not. You need the tapered ones. They’ve been available since the 60’s. The extra 4 mounting holes in these are for the small base Rochesters, Carters, and Holley Teapots. You may need to find what you want by finding them for the small base and not using those holes. . Charlie Price may sell them an maybe Clifford Research. Offenhauser made them back in the 60’s now I’d guess Mr Gasket or whoever owns them..
I think this is the one that you need. https://www.speedwaymotors.com/Holl...B-4-Barrel-Carburetor-Adapter-Plate,5551.html
Thanks for the replies. Would there be any problems with adding a 1" phenolic spacer then on top of that adaptor? Hopefully to prevent percolation when it sits between days I drive it.
Also do you recommend a manual choke or an electric choke. Thanks. I just drive around locally and am used to a manual choke on my tri power set up that I am getting away from. 450 cfm Holley.
Look on eBay, there’s a guy who sells Bakelite carb spacers that are effective but thinner than the plastic ones that Speedway, Summit and and Jegs sell. He offers several different styles. These are the ones that I used on my TriPower. I’ve got them on a couple cars, unless you want a 1” rise.
A 1/4” to 3/8” will do. I use 3/8” under my dual quads from the guy on e-bay.. If you look at your manifold there is a hole behind each of the front threaded holes for the carb. They go into the exhaust crossover and should be open. Your stock WCFB or 4GC’s bottom mount was cast iron and there was a passage for the exhaust gases to past thru. With the old leaded fuel this would carbon up. If open there would be less heat which you need for good atomization. Unleaded gas won’t clog it up. The 450 Holley has pretty small butterflies and most 4 hole 1” spacers have larger diameter holes. Might not be a great idea for efficiency.
Thanks Jimmy Six. That is good to know. Maybe I can get him to make me a thin one with smaller holes.
So being in the building stage on the 8BA and looking to get a manifold from Ed next month I am thinking I can drill through the alum intake to tap into the blocks heat riser orifice so this cavity is functional . Yes I also will use the phenolic same guy in Wisconsin complete kit for $42 I can open it up in the cavity area also . Yes I always liked the looks of the WCFB when I was about 8 I peered into one of two that was on a blown 392 and the guy told me , " Watch out son that will suck you up and spit you out the back ! " Wow was I impressed ! lol . So from what I read of the cooling it would enhance the carbs performance since I am driving long highway miles with this setup

Now your carb flanges look to be iron and the one on mine is aluminum yet everything else on my carb looks to be early style but also flange could have been changed out . I thought mine to be a from a 1954-56 by looking in my Carter Service/Reference Binder perhaps off a Mercury it is a 2016 stamped on the brass tag . My choke unit looks like a gorilla snapped it off at the end of the choke rod and new hot air choke parts are available still looking for a complete original unit the ones with the letter A on the choke cover were available after April 1953 on the Carter 1901 units used by Mercury on the EAC/8CM engines and like to ask if your WCFB choke covers also have an A stamped on them ? If so I may graft the 1901 choke assys to the WCFB. Also looks like on mine it's missing the crossover bowl vent tube I can make one if needed so I've a question . Does your crossover tubes have holes in them above the air horn so that overflow fuel dumps into the air horn from that tube ? Your carbs are a better source of info for me than any image I find online so I'd appreciate if you have a moment and can tell me . I haven't seen any at Vets Stadium last month , and where I got this WCFB well it's the only one there and I found it at the back of a shelf under other carbs it been hiding there for at least 25 years . Thank you Jimmysix and have a nice day
Sorry if I’ve side tracked this thread. I will delete what I have written if asked.. Freddie. The carbs you see on my Y-block are a matched set of 1953 Oldsmobiles. The crossover tubes are for a dual quad Corvette front bowls and are meaningless. The photo I’ve included has a Lincoln on the left and a Mercury on the right. All WCFB’s for Ford products have the vacuum can rear barrels and are a problem. The Lincoln is for a centrifugal distributor and Mercury is for a Loadmatic. The ones for the FMC had aluminum bases as I know it. The Lincoln’s top is 6-1290 the Mercs is 6-1140 they are cast in on the top left rear. I have another Merc with 6-1054 stamped in with NO choke parts. The second photo. I also have 2 perfect Rochester 4GC small base from 53 Cadillacs and a 53 Cadillac WCFB on a 56 Y block manifold I used for 3 years on my 56 Ford. A few these came from the LB swap meet years ago from the Alfa carb shop in Norwalk. Carb King on the HAMB is the go to guy.
Thank you Jimmysix very informative and I will contact CarbKing . Have a nice evening . I should apologize I actually did not realize I started going beyond this thread subject see when I searched for WCFB this thread came up second or third on a list if about 5-8 threads . These threads including this one were HAMBs recommendations for WCFB carbs so is the computer age as Erika is now telling me , " Like a Millennial " So my apologies for accidental upheaval KKrod
