The day after the first episode with your Demon I was riding my Ebike here in North Vancouver and there was a 71-72 Demon parked. It looked to be B5 blue but with a black vinyl top. It was done up exactly the same way as yours Blake….gorgeous car sitting in the sun!
I think you will like the Holley. Better performance with more options for adjustments. Stainless exhaust will give it a nice growl without the drone sound. I'd be interested in watching you build the headers. Sweet ride.
A 340 bored 40 over is well over the safe limits for the sleeves that are in that engine. You better have a really healthy cooling system on that vehicle. But even at that about an hour and a half of driving add your cylinder sleeves are going to be semi-flexible. 340 is a great motor but you cannot board more than 10 or 15 over. At 20 over you're risking making the cylinders too thin. If you have a 6-pack engine, many of them do have a heavier block that allows longer time for heat soak which was the fix for the TA engine. But those were the engines that were actually showing even is a 340 that they were getting excessive blow-by at an hour and a half into a race.
I would like to point out that the reason you cannot put two large a carburetor on an engine, is it will only put fuel in it and meter it by how much air passes through the carburetor. So if you have a 1200 CFM carburetor to feed a 440 and you put it on a 340, it's only going to act blankets on a choked out 440. But it will still meet our fuel just fine for the 340.
Ya I’ve been doing a lot of research on it lately and you’re totally right. There’s a lot of other issues that I’m working through. This car will be a lot of work to get it where I want it. Thanks for all comments! Stay tuned though. Lots of content coming with the demon and plane build
If you do a stroker kit on that engine, I would suggest you put new sleeves in that engine. You would do better to just put a 360 and get the increase stroke of the 360 and then you're looking at about 370 cubic inches. Maybe closer to 368. That's without doing the calculations
That car brand new probably cost about $2,900. And when that car came out I worked on a number of them and had already been working on cars for at least 8 years
I'll bet you if you start that car and look into it you'll see fuel being just dumped into that carburetor probably from the rear set but sometimes it's the primaries that are the problem on those I had a double pumper on a 74 Fury that showed up with that same problem and I quickly figured it out. And that one had a 28 gallon fuel tank. And I've never heard of a demon with anything less than about a 16 gallon tank. So I don't know where you got that small tank, but it doesn't fit that car. My Fury was a police interceptor and I did okay with it I had a clock one time at 187 miles per hour. And could easily Cruise in it and be relatively comfortable at 166 +
Your problem is not the carb, the problem is more than likely the Pintel valve is not sealing and allowing the bowl to fill up and pump fuel directly and through the carburetor. You cannot over carburetor engine. You cannot put a carburetor that's too large for it on an engine. You do have to tune a carburetor to an engine. There's no such thing as having too much carburetor. If your carburetor is pumping raw fuel into the intake. There's a problem with the carburetor. You can change the carburetor and if it has the same problem it's still going to cause you the same headache
Glad it’s running again 👍

Put the cable on a hole a little bit closer to the butterfly shaft. That will give you more than enough stroke to open That Thing Up full
I did that and it’s in another video
Go easy on Peg.
He can take it
