This weekend I became the owner of this very cool looking hemi intake. It has a casting year of 57 on it. I have never seen another intake like this one before. any info on this intake would be great. I think this intake would look real cool on an open hood car. Now I just need a Hemi to put it on....lucky for me I know where one is for a good price.
I think it's a stock industrial type of manifold. If you think your car is to fast and you want to slow your hemi down a little go for it.
If that were mine, I'd get some 1/2" - 3/4" aluminum plate and make a couple of adapters to put a couple of 2GC's on it. The "holes" in the manifold look to be big enough to be equal in area to the throttle plates on a 2GC and it might work well with a little judicious massaging of the manifold and adapters. I have 2 2GC's adapted to a Weiand dual quad manifold on my vintage race car (gotta look old timey, ya' know), and they work very well. I thinkl they're about 350 CFM each. 700 CFM should be just fine for a street engine. Plus, how hard is it going to be to get two matching one barrels that big. 2GC's should be a lot easier to find.
I certainly wouldn't use it on a real 'high-performance" build - and especially not on a 'high-performance"392! But don't toss it in the scrap bin either. With some slight mods it could be still be put to good use and look cool and 'period-correct' on a 50's-style "traditional" rod. There's a guy over on the 'Hemi.Com' list named Rob who's doing this and using one of these intakes on his 331 hemi build - because it happens to fit the 1956 331 truck heads he already has. Stock hemi 'passenger car' intake manifolds - and most aftermarket manifolds too - are designed for standard "passenger car heads which, compared to the "truck heads", have slightly different water passages, a different water-pump/front-cover set-up with a separate water cross-over for mounting the thermostat - and also don't properly cover the bigger heat riser passages in the truck heads. Rob's using the stock 2-1bbl.truck intake with a pair of adapters to mount a pair of large-base 2-bbl. Rochester 2GC's. Two large-base Rochester 2GC's should total out to somewhere around 650-700 cfm and even after being necked down through the stock two 1-bbl-sized carb openings in the manifold it should still flow adequately enough to support around 300-350 or so hp from a 331 or 354 in a street-driven 'hot rod'. You can see some pics of Rod's intake here - www.thehemi.com/forums/viewtopic.php?f=3&t=4258&start=50#p14712 Mart3406 =======================
Do those two pipes running between the carb base flanges normally have coolant running through them to heat up the manifold?
At first, I thought they were balance tubes, but given the huge plenum beneath them, I don't know now. My question is "How did they get them in there?"
They are balance tubes. One carb feeds the upper plenum and the the other feeds the lower. As to how they got them in there ...my best guess wouls be the pipe ends on .the out side of the carb mounts. The where probably pressed in the the wholes sealed with the pipe fittings
This is my 354 hemi 2x1 intake for my 1958 Dodge D400. On this particular setup you can see the governor arm that would attach to a governor mounted on the front of the motor. This carb setup uses the Ball&Ball units. I used to have another governor setup using Holley carbs. The 2x1 intakes were optional packages for the 1957, 1958 & 1959 D700 and D800 trucks. It was standard equipment for the D900. Check out the EFI setup in this report. I think a little adaptation would work well with this intake. http://www.popularhotrodding.com/en...0405em_electronic_fuel_injection/viewall.html
People confuse the truck intakes with the marine intakes. The only thing they have in common is the fact they use 2 one bbl carbs. Other than that, they are completely different. The marine intake is cast in 2 halves, and bolted together in the center....between the carbs. There is no thermostat housing, as water is taken from the sides of the marine intake.
Those one barrell carbs look like stock Carter B & B to me. Shouldn't be hard to find a pair, but probably not much CFM there. I've got a pair on an old Fenton intake that fed a Plymouth six pretty good, doesn't seem like enough for a hemi. I know my 331 sure is thirsty!
does anyone know if one these truck intakes will fit on a '52 331? Sold one a number of years ago, it should work, basically the under carb passage in the head would be the only question. Think the car & marine heads have the same port. I see the photo's are gone from Rob's Thread.
Chrysler Hemi intakes will 'bolt-on' between various years/displacements, but obviously, port mis-match, the t-stat, and the exhaust cross-over are concerns. Physically bolt-on, yes. Optimum efficiency, no. The 51-54 331 is about as close as you will get to a decent fit, given the t-stat housing is already there. .
thank you both 73RR and George. I have been reading a lot of info on the hemis and both of you all ways have good info. I have been looking a several intakes and i forsure want one with the t-stat on it, so that rules out almost all the later model intakes and aftermarket. I really like the look of the 2x1 intake but i didnt know how the ports would line up. Also im keeping the motor mostly original so making more HP is not a concern.
G'day everyone!! First off...I know this thread is very very old, but I'm guessing may be the best place for my question as it refers to this intake. I have two of these intakes with carbs on them stashed away. One has all of the hoses, lines, and linkages still hooked to it, and the other has all the parts, but all taken apart. I've been searching for an old Dodge/Fargo truck shop manual that would have this setup pictured and information regarding the set up, and tuning, but cannot find such a manual so far. I have a collection of manuals from the '53 Desoto up to '57/'58 Dodge/Fargo big trucks, but none of them have any info on this intake. Does anyone know if in fact, there is a manual out there that has this intake in it? Could there be a shop manual that may have the big pumper trucks or something that may have info? *I plan on installing one of these intakes on my 354 truck engine that I have here, and plan on stuffing it in my '30 Chrysler 3 window project. I know it won't be a screaming performance monster, I just like the huge, bulky, 1000lb engine look. Maybe with the right gearing, the torque may make it liven up a bit.* Thank you everyone in advance for any help.
