Ahhh... Blue flame 235. I had one in my '57 Chevy 150. Nice engine.

I wonder if the exhaust that comes out of the EGR port on the back of the manifold would have cooled down enough? I know the exhaust that comes out directly is WAY too hot, which is why the stock setup has the heat riser on it to shut it off above a certain temperature. If it was constantly hot, wouldn't it just cook the underside and overheat the fuel?

I know that this is an insane thought an all...but what about glow plugs? They preheat diesels....And they shut off after a certain amount of time.....

Might be something to look into AB....Of course, I'd assume one would have to drill and tap into the intake, and then fit 6 GP's, etc have all the wiring, etc.....Just a thought....Now expand on it...lol

Hi newbie here, I'm just starting to pull together pieces for my offy/split manifold project and have been thinking about the same issue, and had a thought, has anyone ever had a heated seat apart? Just wondering what kind of elements are built into heated seats, so there you have a 12 volt heat source.....

Wow, I'd hadn't even thought of that. If they're a coiled wire, it might be something you could just wrap around the intake itself. Might have to look into that.

It's a type of ceramic plate....Not a simple coiled wire...

I believe I actually contacted them about those pad heaters back when I was originally looking at the idea. They said it wouldn't work very well as it doesn't heat up very quickly (claims it can warm up oil from below freezing in just under 2 hours) , and don't get all that hot.

We need around 200° or so, and those only get up to around 50°-ish. Just enough to keep the oil warm and thin.

You've prob mentioned this and i didn't see it, but : While browsing I came across a kit that Clifford used to sell for the purpose of heating their intakes. It was a plate, like used for coolant, but they supplied fittings and copper tube that the owner was supposed to drill into their headers or pipes, and soldier on, thereby supplying exhaust heat, fast and furious to the underside of the intake. I've since seen one or two Cliff's around with the tubes attached.

Of course the new Clifford's have a provision for coolant.

There is an install like this on the local craig'slist.

1981 ford 1/2 ton 4x4 6cyl.

It runs good, but is running a little rich currently...Not a bad buy actually

Something like that would be nice. I actually tried to look up something like that originally, but couldn't find anything that was dry. Most everything was for some tank that heated the liquid around it. In return, the liquid kept the heat dispersed and kept it from burning up. Thought about wrapping the intake in coiled copper wire, but then came upon the issue of temperature control. How to cut the current once it reached a certain temp, etc.

Do you have a link to this setup?

That's not a bad buy at all. The cost of the carb, intake, and headers new is over that price.

I'd like to see someone with mad fab skills throw together an exhaust heated box that includes a functioning EGR valve for the Offy intakes.

Anybody know what the temperature of the manifold should be for optimal atomization? Having it too hot is probably not a good idea either. According to the web, gas boils from 100-400 degrees F depending on a bunch of variables.

Would be nice to have a way to control the carb heat.

Here is a photo of a system similiar to what Cliffords used to sell. This is of a Chevy intake, so I hope the photo won't burst into flames here. The actual Cliff. system has two copper tubes welded into the headers. Cheers.

This is a old thread but someone might be able to use the info on carb and manifold heat found here
