im having similar probs but some days run good and somedays spark knock even with 93 octaine fuel have long tube headerswith the duels ran side by side! the fool i got it from welded o2 sensor in and butchered wires! either i got a bad o2 whitch i have to cut out or headers and duals lean mixture too much. what i cant figure is why one day runs like a champ then all the sudden ping ping even on a cold motor?????thinking it is pollution crap in back of heads cause i have a leak in exhaust but cant find it by changing gaskets and collector?? anyone pulled this crap off with any luck????

Being an electrical engineer with hybrid controls background (analog/digital), I'm no stranger to closed loop control either...
8N Ford tractors - hoooray! I am a Farmall and Ford tractor enthusiast myself. I've done a Cub and an 8N. But, but... the 8N was built between '48 (late '47 actually) and '52. In '53 a significant redesign (overhead valve engine, live hydraulics) became the NAA. By '55 they were producing two different sizes, the 600 series and the 800 series. Was your '58 maybe a '48?
