I recently bought a 2711 edelbrock intake for my 68 350 with 4bbl. In an attempt to keep the factory choke, I made this bit to put on the aluminum intake, thinking about having a friend tig weld it, but I’m worried about the porosity in the intake, and also thinking about just using jb weld. Any thoughts or ideas would be greatly appreciated.
Is that a much easier solution? I thought I was being slick, but it’s probably more work than it’s good for, and won’t look as clean. I made this jog off the factory manifold to hold the choke housing in the correct location as well. I made sure the thermo choke fits in the housing and has full range of motion. Mainly switching to aluminum intake so it’s not such a pain to remove the intake with the motor in the car
After looking into the electric choke I think that’s the way I’ll go, I didn’t even know that was an option. I guess it was still a fun learning experience. I made the program and cut it on our 5 axis water jet, and also used our Bridgeport for the first time to do a little bit of milling. I got a little overzealous with the feed rate at one point, and launched the piece out of the vise, which was a pucker moment. But overall fun experience. Thank you for the advice, Tony
I like your idea, I’d use it especially since you already made it. I do prefer mechanical over electric with most things, both my vehicles that have a quadrajet have hot air choke with a tube going down to the exhaust to solve the divorces choke stove/aftermarket intake issue.
I'd say it comes down to how you want it to function vs. how you want it to look. If function is your priority, I wouldn't hesitate to put an electric choke on it. It'll heat up and deactivate (open) smoother and quicker than the old mechanical set-up. Your original divorced set-up was designed for the thermal profile of the original iron intake. The aluminum will be much different.
You did a good job machining that divorced adaptor piece. It'll look closer to the original set-up with that but I think the electric choke will almost certainly function better.

I was worried about the different in heat transfer, between iron and aluminum, as well. Thanks
If you weld the intake, it will almost certainly warp at the intake gasket surface. Resurfacing it would cost up to $300 and a leak at the heat riser port would be undesirable.

That was why I was leaning towards jb weld, but it wouldn’t look very nice, and there’s still the concern of having the right heat transfer. Leaning more towards the electric choke
