If you > Thanks for drilling the suggestion in, Pat. I'm going to try that next (although I was not able to get it to fail at temp last night). I have been distracted by odd wiring splices and checking all of the grounds (but I don't think I wasted any time tightening that stuff up). I have found a local source for the cyl head temp sensor - Bosch 0 280 130 003 for my "B" brain, right? Even if it turns out that that sensor is not the culprit, I'll be glad to have a spare. And Jim, on my '69 the cyl head temp sensor is mounted on top of the head by the #4 spark plug. And I noticed that my case # corresponds to something 1971-ish. Last spring the PO told me that he had a recent rebuild done (must've used the good lifters, because my valves don't loosen up). Obviously used the later heads. The #1 and #2 injectors are grounded to the top of the case, but the #3 and #4 are grounded on the tin by the #4 plug. A strange arrangement. And on that #3/#4 ground, there *is* a spring washer in there, and it is holding tight. My wife has named the car Lucille, reference to the old C&W song "Ya picked a fine time to leave me Lucille..."
