I sure stirred up a hornet's nest here. I went to NAPA and picked up a 703-1411, 7 lb cap. It has the 1" drop and worked fine - Cost $5.77. Took the Packard out this afternoon up a 13% grade, the gauge went up to the "P" in temp, and then back down as soon as I was on top of the hill. Made about a 15 mile trip, which previously would end in boiling over. No problems today. However, I also added a bottle of "water wetter" which is supposed to make the water more able to transfer heat. I should have done one at a time, but so far I'm happy. No more boiling over. thanks to all.
