Yeah I bought them off Summit and it said 220k but now i see there's a possiblity that's wrong. I wonder how to find out...

Well, the ARP's are not actually 220,000PSI as you said Bill. I don't doubt they'll still do their job though.
This morning I got my adapter and hacked manifold back.
It also leaves room in the future to drop an external wastegate out of the pipe. It's very thick walled steel and he did an awesome job forming it.
How did you come to the conclusion as to where to cut the manifold? Also, was the manifold cut with a band saw, machined or both?Well, the ARP's are not actually 220,000PSI as you said Bill. I don't doubt they'll still do their job though.
This morning I got my adapter and hacked manifold back. The original custom header design was scrapped due to time constraints and the person welding them was very hard to keep contact with. Oh well though, this was plan B, I call it the Surge Pipe, even though I've seen a few people make these. (It's like a part that skips the pishta pipe)
Anyway, I had the idea, and dropped it off to my favorite exhaust shop, and after three weeks he finally made the flange adapter to holes I drilled and tapped, and it will hang with a U bolt as well going through the intake holes that used to hang the exhaust manifold and the kickdown lever. It should be fairly sturdy. He also made a custom block off plate to get rid of the open choke pocket cover. I coated all three pieces with ceramic and ordered some exhaust gasket material, tomorrow I'll go to the hardware store and source some G8 bolts for all of it.
All in all - I'm very happy with how it turned out.

Sorry for the delayed response. Work has been fairly busy and I don't check on much online. BUT NOW I am ramping back up with the Dart. It's getting painted, new engine I am in the process of assembling, etc.How did you come to the conclusion as to where to cut the manifold?

Love your work Serj!
To boost reference the power valve you need to literally disassemble it and reassemble it backwards with the spring moving it on the other side. Its kind of weird sounding and i dont have a pic of what i did, and then you also block off the lower vacuum port in the powervalve cavity. Then i drilled a 1/4" hole through the side of the carb into the dame cavity and inserted a tube that goes to the caeb bonnet, so when boost pressure overcomes the spring, it opens the valve. Theres also someone who makes the valves for $35 on the turboforums but i forget who. Its not a bad deal though.I LOVE yer build & looks top shelf! I too am under taking a boosted /6 in a 73 duster so your thread is great! I have one qustion for ya. What mods did you do to boost ref the power valve in the carb? Thats a 350 cfm correct? Thanks! Keep it up!

I just wanted to say thank you for doing this thread. I'm currently on page 15. I intend to read the entire thread. I'm taking a lot of your lessons learned and some from others you referenced. My intention is to get my 63 Dart 3 on the tree turbo'd and fuel injected. I can't wait to get started. What you've done with minimal hand tools and in a driveway is amazing.
