Wow, learn something new everyday. Now that I've read up on this cross-fire problem, it could very well be my problem. I'll look into the cap as well as separate the wires better.
Also, did anyone who looked at the close-up picture of my engine wiring see anything funny about the distributor? After I cut the wires, I noticed that my vacuum advance horn was pointing toward the front of the car, not the #4 cylinder like most small blocks. The previous owner put the distributor in one cylinder off. It runs ok, but the vacuum advance horn is shoved up against one of the manifold runners, making it a tight fit. The more I go through this car, the more "odd things" I find about the engine set up. Of course if I try to set the distributor to the usual location, some of the plug wires will be a little off. Oh well, live and learn.
