The old made early Hemi Weiand dual Carter intake is that bored for the older square bore or the spreadbore ? If I get it right the pre 57 had the square bore carbs but the Chrysler 300 in 57 had the spreadbore. The 392 intake look as as a Weiand but the early Chrysler dual Carter has another design. Nothing wrong sith square bore, just did like to get the information. I build upp a std 392 for a hotrod but little more comp/cam then it feel odd to use the older carbs on it. Look for a old Weiand intake but can’t find one, but this question came upp.
A buddy restore a engine to a customer, its a 57 300C convertible, but its has a 354 but look at the intake, its a 2-7-57 cast 7 February ? ( 392 ) intake and ports is equal so no spreadbore ( a 392 had AFB carbs so intske must been spreadbore std - or ) and carbs is the older Carter.
The old 7263 must been spredbores and the one I seen in Sweden has another number WC2QE must bee squarebores.
Has anyone a 300C 392 intake so I can see if the holes is drilled for spreadbore as Chrysler had the AFB 1958 ( spreadbore ) but the 392 came 1957. This is a intake cast in 57 and its a true 300C and look at holes, equal, so no spredbores. Carbs is std the small Carter squarebore. Ideas ? -So how look at cast in 1958 392 intake ?
I have quite a bit of 392 stuff, but no dual-quad intakes . . . so I can't help yah. Are you going away from your initial flathead idea to a early Hemi? That sure changes your build parameters by a bunch!
No, I was helping a nostalgica dragster customer install new caps, bore/deck, O-ring and order a Bryant crank, balance etc, and as a Hemi dude ( 426 Hemi ) I got into get one to look at in the shop, so I found a 354 ( was have a crack ) so I sold it and bought parts to a 392. Build up will be most with the std parts but little more cam and comp and maybe a Hot-Rod intake, but I don't say no to a std 300C intake either. Plus information is never hard to bare. Idea was a second ch***ie to my 5W body, but it will has the FH as being machined now. So if the Hemi comes into the coupe later on time will tell. But as we speak. I might found a old Weind intake here in Sweden and its the square bored version. So I has found carbs in USA ( the small ones at 3-400 CFM ) I guess it's 'better' to go for the 58 style AFB spread bores, as maybe more 'street' drives. But if not going into that plus the Weiand intake is square bore and I don't like use adaptors. So what is your ideas on this old smaller Carters on a aplication ( rather hot profile cam and 10.5 in compression ) and see it as a Hot-Rod engine.
If I get a Weiand, should I get the squarebore ( I know of one ) or wait until I find the spreadbore Weiand #7263, I showed picure about above, or is the cool thing with the early/er squareport intakes Weiand made (?) I also showed a picture on. I guess to find a spreadbore std 392 intake will be Very hard. I located up one std but its 1956 354 300C. Se picture in a book.
If I get it correct the AFB that came out 1958 is a 'spread-bore' carb. The intakes I showed as Weiands WC2QE and the std 300C ( 354 ) number #1634285 and the std 300C 1957 number #1733477 seems to be all 'square-bore' = equal 4 holes. So question is, how does a 58/59 392 intake look like ? I might bought the Weiand WC2QE intake, but I do need find a set of the old small Carters. If anyone has a set, keep me posted.
Is that a std intake or a new cast Weiand ? If a std, how did the holes look ? As I mentioned I like the old smaller Carters as the intake is vintage and made for the small ones. Yes I could use adaptors and find old AfB’s, but 800 cfm will be fine. My coupe is build with only vintage parts and transmission is a Lasalle and old Cragar adaptors. As open hood sides the carbs will be seen so in my world its better to use the old small Carters. Yes the cores and rebuild will be higher than get 2 new Edelbroks. Shore best way is a new Wiand intake and 2 new carbs, new starter, new alternator, Chevy BB water pump, ATI damper, a 727 automatic and a Ford 9” and in coil overs. -But I try do it the hard way.
To my knowledge, ALL Carter AFB carburetors were squarebore, except the 3636s (trapdoor) 3 barrel. Jon
Jon, I has only before deal with the 383 AVS Carters or the 426 Hemi AFB Carter carbs or aftermarket NHRA legal and they are spreadbores. Before I cash out 2K ( yes you heard correct = its really ridicules ) on the square bore vintage Weiand intake. My plan is run the 2 smaller Carters pre 58 ( max 400 cfm ) as they fit the intake but that means 800 cfm but I heard in reality if one go dual pressuare is not that way so it means even dual carbs 400 x 2 its not get that cfm to the engine so maybe a hair more than 400, and if so that sounds to me very small for a 10 in comp and a hot cam 400 cubics Hemi. Ideas (?) But I know back then it was often 3 Stromberg 97 ( ex the Cragar or Hourne intake ) and that was 155 x 3 = 465 cfm but again it would not be that much ( to engine ) ( again, yes I know there are adaptors to use the 600 cfm AFB’s on this Weiand squarebored intakes.
Just to be accurate, this is what a true spreadbore intake looks like (x2). The others mentioned are; an early square bolt pattern for early Carter WCFB, Rochester 4 bbl, and Ford “Teapot” Holleys (the flathead screw pattern above). There are two later rectangular patterns, one for Carter WCFB/AFB and Rochester 4-Jet, and the other rectangular pattern is the well known Holley/Ford 4100 pattern. There are probably some other obscure 4bbl carbs (Stromberg?) but those are the common hot rod carbs. No offense intended but terminology can be important, especially when gathering old speed equipment. (image from thecarburetorshop.com)
The spreadbore intake ( Offy on picture above ) is not a early Hemi. -I wish someone had a 58/59 std 392 intake to show ! The later Weiands 7263 look like this and boltpatterns are to AFB's, and a older vintage 7263 look like this. The one I can bought is squarebore ( 4 equal holes and fit the WCFB Carters )
These days Id buy what ever I could find that was remotely reasonable priced . An adapter on a aftermarket intake would not be a deal breaker.
Although a lot of AFBs had secondary throttle plates that were .25 inches larger in diameter than the primary throttle plates, they're still not considered a spread bore. Are you confusing this nomenclature with the different bolt patterns of the intake manifolds in question?
I think I solved some question here. The vintage Weaind intake had 2 partnumbers. The one I think I will bought is the 4 equal round holes and I plan use the small Carters on it. Yes I can use adapter plates and find 2 AFB's. I think that will be fine with the small ones std build-up and Cragar adapter plates and a 39 Lasalle transmission and a Schefer flywheel. This is more for the looks and no racing, it still will produce allot of HP. The coupe is traditional and even if no good idea I think I keep the std 32 rearend. I seen/heard many used that on hot/street rods on 50's, 60's and up. -I still like to see how the 392 std intale look like, maybe they had also 4 equal holes or 2 small and 2 bigger, maybe CC bolts is different as the larger AFB.
