Ok running dual single barrel intake. Also running set of tube headers. The intake manifold has a home made heat plate installed however I don't know how I would apply heat to help vaporize the fuel. I know that this can be done just looking for ideas as to how others have don this. Picture are worth a thousand words. Thank you... it's 235 I6 dual Offenhauser intake with single Rochester carbs. and a set of "Hot Rods" tube headers.
Someone has to have some way to make this work. Maybe I should ask to see what others are running for carb/intake heat. I know the Edmonds intake has water running into it... let see what you got...
I take it the headers you have don't have the bungs in them to hook up the exhaust heat? I am unfarmiliar with the brand you describe. If you are having a hard time getting exhaust to the heat plate, you could heat it with water.
Doesn't the intake have a provision for running water through it? If it doesn't, I'm stumped as to how to do it. BB
Could the heat plate be for the choke? It works ok most places to blank it off and let engine heat warm the carb up. I drive my roadster in below freezing weather fairly often. With an electric choke on the lean jetted Edelbrock 750 it's not a problem. Just don't roll the throttle on too far until you have a mile or two on it and don't floor it until the engine is fully warm. If the engine sneezes you went too far with the throttle.
Somewhere I have seen pics of a piece that clamps to a header tube and has a hose bung [ wrong word ] that is used to bring heated air to an oem style airfilter .
462" late Buick - .030 over 455. About 530# of torque. It ran good with a pair of 500 cfm Carters up top and a bigger cam. Then: Now: Kenne-Bell recommended two 750's when I was ordering parts. The big Buicks like lots of carburetion in most any state of tune. I have another 750 waiting in the wings for when I get the 31 on 32 rails car running. The big cam and twin 500's go in/on that engine and I'm gonna give the dual 750's a shot. I don't want to highjack the thread too far, but Edelbrock/Carters are somewhat self limiting in the intake area. The secondary air valve only opens as far as the engine requires.
I've made them from exhaust tubing welded into a box and welded or clamped onto a header primary. Here's a pic of a stock 455 Buick heat pickup device. Bolts to the head here, but it could be adapted to a header easily enough.
Ok because I'm horribly new to this, I most likely haven't given all of the information. The headers have a bung in both of the header pipes. It's just a fitting welded to the pipe and it's opening doesn't go into the exhaust path. It's just a fitting welded ON the header tube. I believe that it's ment to be for heat pipe but I'm not sure. I believe that comming off the header would more effectively heat the intake. Exhaust will be hot from the instant that the engine is running. If I used water the temp would vary a bit with temprature and thermostat opened and closed and in the morning when it's cold would take some time to maintain a steady temp. The OFFY intake that I have has a plate on the bottom like the stock manifold has. I always thought that this provision was for heated air not heated water. Correct me if I'm wrong.... Lets just say that my headers have this bung weleded in there for Heat tube. With out it being through the header wall to the exhaust path will it still supply enough heat to effectively heat the intake manifold?
yes that is what the bungs are for and that is what you should do. Have you gotten one of Patrick's catalogues? If not that is the first thing you should do - then buy his parts because he is helping you. There is a TON of info in there on inlines. The second thing you should do is join Inliners and hang out on out bulletin board. Do a search - like you should have done here first - all this stuff has been beat to death. You might have to dig a little to find the answers, but all the info is posted several times over on both boards. Keep your inline - they are fun engines!
FWIW the Inliners site host is 'upgrading' their server and the site is running slow. I would expect you would have to drill into the header to get enough exhaust heat for the intake. How big a hole, I don't know.
I use water heat on my 235 - I don't like the idea of corrosive exhaust g***es running through an aluminum manifold. Takes a little longer to warm up but that's the only down-side
6inarow, I've bought from Partick's and their catalog is on it's way to the house. Sorry if i've asked question that others have already ask. If it's a topic that has been beat to death I will refrain fron asking about it any further. This site more so than any other has offerings that are not available on other sites. If there are topics that on occasion come up that have been alredy addressed offer some links. I personally didn't find them. But maybe my search wasn't effective due to wording or nomenclature. Thanks for your ***istance. As for what I should have done, well you have no way of knowing that I had or had not. Thank you however for your insight on the matter. Regards......
Soba 03, I guess I owe you an aoplogy. sorry for jumping on you. I just ran a search of "235 dual carb heat" and came up with 75 threads (Not posts, but threads). As you probably already know, not all the threads will apply, but you get the idea. if you ran a different search you will undoubtedly come up with more. I dont know how to post the links, as I am a computer dumb ***, maybe someone else can help. but here is what I found before I even got to the bottom of the first page: 1. Chevy manifold question by jabsled 2. hopping up a 216 inline 6??? by fat49chevy 3. 235 Offy dual intake help needed by Danimal 4. Question about a 235 I6 in a 54 Chevy by KarlsKustom all of these have something directly related to what you asked. Yes, you are right about the offerings that this site has - there is no question about it. You are also right that I have no way of knowing what you what you had or had not searched. But I am a self proclaimed computer ***** and I found it.

6inarow, I'll give you that I should not have come back at you and I'll say it to you and the rest of the board, sorry bout that... my Skin is normally much thicker than that... I'm over it... thank you for the links... Regards!!!!!
