Fired it up - D100
Been working away as time allowed on the D100, and finally fired it tonight. It was just as much fun as ever to hear that thing come to life. I had a couple of problems when I first attempted to start it.
The truck originally had a points distributor and I wanted electronic, but I didn't have an extra Mopar ignition box plug or harness, so I stuck in a Mopar distributor converted with an HEI module. Figured it would be good, and easier to wire with 12v no ballast. I even wired it on the bench and tested it with two old Accel coils and a Davis coil and spun the dist to see which gave the hottest spark. Went with one of the Accels. Put it all in the truck and no spark. Wiring tested good, so I pulled the dist and changed the magnetic pick-up and reluctor from another Mopar dist, and still no spark.
I had an MSD E-Curve dist for a SB Mopar, and decided why not? Set the pots inside for the advance curve I wanted and set the rev limiter to 7500; it was super easy to wire in. Since it had an HEI cap I had to use different wires, but I had a set off a DUI. Fired right up and sounded stout with the open headers. I had to free rev it a few times just to hear the secondaries on the big 850 TQ kick in, and it pulled clean. Idle was nice and steady too. I kind of rough timed it by ear, and the carb still has its bench settings from the rebuild.
Heater control valve leaks, so I need to fix that, and it is open headers as I still need to build the exhaust. I have the instrument panel pulled to fix the dash lights, so no gauges, and I didn't want to run it long with no indication of oil pressure, but I'm pretty sure its probably OK. Need to charge the A/C and I'm going to build a single snorkle ram air to the front apron. As long as I've been doing this stuff it is still exciting and fun to hear a fresh engine fire for the first time!
