Slant 6 Turbo 68Dart Project
Bill, I have an MSD-6 ALN, and a Mallory (4 I believe?) that I can pick between to run. The distributor I'm using currently is the Mopar Points Dizzy, with a Pertronix pickup and trigger installed. The advance governing plate has been welded closed slightly to allow for 8* advance, and the initial is set to 10 advanced under no vacuum. With the vacuum advance hooked up and a good rev, it will get up to about 34 degrees advanced stated by my dad's Snap-On timing light, where I back up the timing on the light till it hits 0. Once boost is on I'm assuming it just drops to 18, but no real way to tell that. I want to experiment with the Volvo unit I have as well to see if I can allow the governor plate to be opened up a bit if the pod is going to retard the timing. It may only have 5* of control though.
Yesterday, I made a spark plug swap. The ones in there had a .028 opening, and I gapped some new plugs to .035 and just tried what the engine guy recommended. It started on the first try this time in the morning, and idled fine, and did not shut down like usual (which is common in the morning, then a restart will make it run fine).
I also had to retune and adjust the carb and everything because the idle was much smoother now and the engine was running at about 1200RPM curb idle. I managed to drop it to 800 which is the lowest I've gotten it with the turbo setup installed. I drove it around. It seemed good. I also discovered the vacuum leak - right at the base of the carb. The plate that mounts to the intake to adapt the carb seems to be a little loose. I'll have to disassemble and tighten it down and find a way to make it not come loose again.
