Slant 6 Turbo 68Dart Project

As much as i like soldering (I fixed a few dumpster flat panel Tv's that are now In my house) I'd rather get something a bit more plug and play.

I found a Mallory Hi Fire VII (Part no667), but can't find any information about it. It has a rev limiter setting, and from what I've seen of the more modern boxes, a retard control somehow. But I can't find any info on it. ALl that comes up is the 667c or 667s which both look like completely different units. This one purely says Hi FireVII with no letters after. Would this work, or keep hunting?

EDIT:
Well, I finally found the oldschool Mallory instructions, and the regular 667 is only for V-8s while the 667-6 will work with a 6.
I'm still hunting for one of the add-on able ignitions like this because there is just so much I can do with them to adjust. Boost controllers, rev limiters, etc...
But if it all comes down to it, HEI is just gonna happen...
Also This is where I'm at on the downpipe, I bought a 3" to 2 1/2" reducer for $2.00 to use for the start, even though the exhaust outlet on the turbo is only 2 1/2" because I wanted to be able to angle the pipe from the start, allowing the next piece to be directed away from the fender. It worked well. I shave about a 25 degree angle into it and mounted it. Looks straight - but it's not. I put the sensor bung in a way that it would not stick straight up but at an angle.

I cleaned the galvanization off the flex pipe with a sander, and then welded it to the adapter. I felt using a clamp that close to the turbo would look cheesy. It was very difficult to weld the thing tubing, but it worked. I since cut the flex in half as it was way too long, and will do the 45* dive there, and the wastegate pipe should come up and meet it... but still not decided on that whole wastegate pipe... I'm thinking about tying the downpipe to the mount on the J pipe, so that I can support the whole system on one large 1/4" thick steel bracket. This thing is heavy afterall.
