A tech update, but without any pictures, sorry, nothing snazzy on this one to take pictures of. So I removed the Pertronix 1662 from Distributor 19100-61180 and installed the Pertronix 1662LS. It was a gutless wonder on my test drive, but no worries. The Lobe Sensing version fires the coil at a different point, so I hooked up the timing light and tried to advance the timing a bit. I couldn't because the cap hold down clamps were driven into the push rod cover. But still no worries. I pulled the Distributor up and advanced it one tooth into the cam gear, and brought it back down, luckily still engaging the oil pump. Then I had plenty of room to set the timing back to approx. 10* BTDC and Voila, that did the trick. Now... I didn't realize how crappy my idle had gotten until I did the upgrade. It was really bad before, but I thought it was just the best it could be. Nope. It is rock solid now, it just hums. And I'm back to full power on the acceleration after I got the timing back in spec. Just an amazing weekend all together. That Pertronix 1662 was really causing problems that were going to get worse, the shavings from it grinding into the base of the pickup plate were into everything! And now I know.
